     * [48]155 comments

   Today, we’re launching our first microcontroller-class product:
   Raspberry Pi Pico. Priced at just $4, it is built on RP2040, a
   brand-new chip developed right here at Raspberry Pi. Whether you’re
   looking for a standalone board for deep-embedded development or a
   companion to your Raspberry Pi computer, or you’re taking your first
   steps with a microcontroller, this is the board for you.

   IFRAME: [49]https://www.youtube.com/embed/o-tRJPCv0GA?feature=oembed

   You can [50]buy your Raspberry Pi Pico today online from one of our
   Approved Resellers. Or head to your local newsagent, where every copy
   of this month’s [51]HackSpace magazine comes with a free Pico, as well
   as plenty of guides and tutorials to help you get started with it. If
   coronavirus restrictions mean that you can’t get to your newsagent
   right now, you can [52]grab a subscription and get Pico delivered to
   your door.
   Oops!… We Did It Again

Microcomputers and microcontrollers

   Many of our favourite projects, from [53]cucumber sorters to [54]high
   altitude balloons, connect Raspberry Pi to the physical world: software
   running on the Raspberry Pi reads sensors, performs computations, talks
   to the network, and drives actuators. This ability to bridge the worlds
   of software and hardware has contributed to the enduring popularity of
   Raspberry Pi computers, with over 37 million units sold to date.

   But there are limits: even in its lowest power mode a [55]Raspberry Pi
   Zero will consume on the order of 100 milliwatts; Raspberry Pi on its
   own does not support analogue input; and while it is possible to run
   “bare metal” software on a Raspberry Pi, software running under a
   general-purpose operating system like Linux is not well suited to
   low-latency control of individual I/O pins.

   Many hobbyist and industrial applications pair a Raspberry Pi with a
   microcontroller. The Raspberry Pi takes care of heavyweight
   computation, network access, and storage, while the microcontroller
   handles analogue input and low-latency I/O and, sometimes, provides a
   very low-power standby mode.

   Until now, we’ve not been able to figure out a way to make a compelling
   microcontroller-class product of our own. To make the product we really
   wanted to make, first we had to learn to make our own chips.

Raspberry Si

   It seems like every fruit company is making its own silicon these days,
   and we’re no exception. RP2040 builds on the lessons we’ve learned from
   using other microcontrollers in our products, from the [56]Sense HAT to
   [57]Raspberry Pi 400. It’s the result of many years of hard work by our
   in-house chip team.
   RP2040 on a Raspberry Pi Pico

   We had three principal design goals for RP2040: high performance,
   particularly for integer workloads; flexible I/O, to allow us to talk
   to almost any external device; and of course, low cost, to eliminate
   barriers to entry. We ended up with an incredibly powerful little chip,
   cramming all this into a 7 × 7 mm QFN-56 package containing just two
   square millimetres of 40 nm silicon. RP2040 has:
     * Dual-core Arm Cortex-M0+ @ 133MHz
     * 264KB (remember kilobytes?) of on-chip RAM
     * Support for up to 16MB of off-chip Flash memory via dedicated QSPI
       bus
     * DMA controller
     * Interpolator and integer divider peripherals
     * 30 GPIO pins, 4 of which can be used as analogue inputs
     * 2 × UARTs, 2 × SPI controllers, and 2 × I2C controllers
     * 16 × PWM channels
     * 1 × USB 1.1 controller and PHY, with host and device support
     * 8 × Raspberry Pi Programmable I/O (PIO) state machines
     * USB mass-storage boot mode with UF2 support, for drag-and-drop
       programming

   And this isn’t just a powerful chip: it’s designed to help you bring
   every last drop of that power to bear. With six independent banks of
   RAM, and a fully connected switch at the heart of its bus fabric, you
   can easily arrange for the cores and DMA engines to run in parallel
   without contention.

   For power users, we provide a complete C SDK, a GCC-based toolchain,
   and Visual Studio Code integration.

   As Cortex-M0+ lacks a floating-point unit, we have commissioned
   optimised floating-point functions from Mark Owen, author of the
   popular [58]Qfplib libraries; these are substantially faster than their
   GCC library equivalents, and are licensed for use on any RP2040-based
   product.

   With two fast cores and and a large amount of on-chip RAM, RP2040 is a
   great platform for machine learning applications. You can find Pete
   Warden’s port of Google’s [59]TensorFlow Lite framework [60]here. Look
   out for more machine learning content over the coming months.

   For beginners, and other users who prefer high-level languages, we’ve
   worked with Damien George, creator of [61]MicroPython, to build a
   polished port for RP2040; it exposes all of the chip’s hardware
   features, including our innovative PIO subsystem. And our friend Aivar
   Annamaa has added RP2040 MicroPython support to the popular [62]Thonny
   IDE.

Raspberry Pi Pico

   Raspberry Pi Pico is designed as our low-cost breakout board for
   RP2040. It pairs RP2040 with 2MB of Flash memory, and a power supply
   chip supporting input voltages from 1.8-5.5V. This allows you to power
   your Pico from a wide variety of sources, including two or three AA
   cells in series, or a single lithium-ion cell.

   Pico provides a single push button, which can be used to enter USB
   mass-storage mode at boot time and also as a general input, and a
   single LED. It exposes 26 of the 30 GPIO pins on RP2040, including
   three of the four analogue inputs, to 0.1”-pitch pads; you can solder
   headers to these pads or take advantage of their castellated edges to
   solder Pico directly to a carrier board. Volume customers will be able
   to buy pre-reeled Pico units: in fact we already supply Pico to our
   Approved Resellers in this format.

   The Pico PCB layout was co-designed with the RP2040 silicon and
   package, and we’re really pleased with how it turned out: a two-layer
   PCB with a solid ground plane and a GPIO breakout that “just works”.
   A reel of Raspberry Pi Pico boards Reely good

   Whether Raspberry Pi Pico is your first microcontroller or your
   fifty-first, we can’t wait to see what you do with it.

Raspberry Pi Pico documentation

   Our ambition with RP2040 wasn’t just to produce the best chip, but to
   support that chip with the best documentation. Alasdair Allan, who
   joined us a year ago, has overseen a colossal effort on the part of the
   whole engineering team to document every aspect of the design, with
   simple, easy-to-understand examples to help you get the most out of
   your Raspberry Pi Pico.

   You can find complete documentation for Raspberry Pi Pico, and for
   RP2040, its SDK and toolchain, [63]here.
   Get Started with Raspberry Pi Pico book

   To help you get the most of your Pico, why not grab a copy of [64]Get
   Started with MicroPython on Raspberry Pi Pico by Gareth Halfacree and
   our very own Ben Everard. It’s ideal for beginners who are new (or
   new-ish) to making with microcontrollers.

   Our colleagues at the Raspberry Pi Foundation have also produced an
   educational project to help you get started with Raspberry Pi Pico. You
   can find it [65]here.

Partners

   Over the last couple of months, we’ve been working with our friends at
   Adafruit, Arduino, Pimoroni, and Sparkfun to create accessories for
   Raspberry Pi Pico, and a variety of other boards built on the RP2040
   silicon platform. Here are just a few of the products that are
   available to buy or pre-order today.

Adafruit Feather RP 2040

   RP2040 joins the hundreds of boards in the Feather ecosystem with the
   fully featured [66]Feather RP 2040 board. The 2″ × 0.9″ dev board has
   USB C, Lipoly battery charging, 4MB of QSPI flash memory, a STEMMA QT
   I2C connector, and an optional SWD debug port. With plenty of GPIO for
   use with any FeatherWing, and hundreds of Qwiic/QT/Grove sensors that
   can plug and play, it’s the fast way to get started.
   Feathery goodness

Adafruit ItsyBitsy RP 2040

   Need a petite dev board for RP2040? The [67]Itsy Bitsy RP 2040 is
   positively tiny, but it still has lots of GPIO, 4MB of QSPI flash, boot
   and reset buttons, a built-in RGB NeoPixel, and even a 5V output logic
   pin, so it’s perfect for NeoPixel projects!
   Small is beautiful

Arduino Nano RP2040 Connect

   Arduino joins the RP2040 family with one of its most popular formats:
   the Arduino Nano. The [68]Arduino Nano RP2040 Connect combines the
   power of RP2040 with high-quality MEMS sensors (a 9-axis IMU and
   microphone), a highly efficient power section, a powerful
   WiFi/Bluetooth module, and the ECC608 crypto chip, enabling anybody to
   create secure IoT applications with this new microcontroller. The
   Arduino Nano RP2040 Connect will be available for pre-order in the next
   few weeks.

   VBUS is the 5V USB input voltage. VSYS is the ‘system’ input voltage
   used to generate 3.3V. On the board VSYS is fed from VBUS via a
   Schottky diode. Feeding external power in via VSYS (through another
   Schottky diode) allows eithre VBUS [if connected] or your external
   power [if connected] to power the board, whichever is the higher
   voltage. It’s designed to be simple but flexible.

   Gold plated pinheaders are relatively expensive, and the moon shaped
   edge indentations make soldering the board directly to a carrier easy,
   no pinheaders needed.
   But I suspect other board makers will sell versions with headers.

   Please, two more questions: what is “integer divider peripherals”? And
   what are the new floating-point functions? Where do they live and what
   does it mean “are licensed for use on any RP2040-based product”?

   Integer divide peripheral is fast internal hardware to do integer
   division. The floating point functions are hand-optmised assembler code
   to do floating point operations, faster than defaults included with GCC
   etc.

   I know it’s a bit early but is it possible to shed more light on both
   the integer divider and FP routines? What the divider developed
   in-house? How many cycles does the division instruction take? Is it
   64-by-32-bits or 32-by-32 bits? And the FP routines, are they open
   source? What license? Are they IEEE 754 compliant? Can they be used
   with other M0-based processors (in proprietary applications, for
   example)?

   If they were open source they’d be licenced for use on anything, not

   The Divider routines were developed in house, they are fully described
   in the datasheet. In addition there is HW PWM (this one is pretty
   cool), and a HW interpolator. And the PIO is very novel and clever.

   You can set up your application so that the Pico acts as a USB serial

   connected, just the USB. But that does mean you cannot use the USB for
   other purposes.

   I read from the datasheet:
   4.7. USB
   RP2040 has an integrated USB1.1 PHY and controller which can be used in
   both Device and Host mode. Pico adds the
   two required 27 ohm external resistors and brings this interface to a
   standard micro-USB port.
   The USB port can be used to access the USB bootloader (BOOTSEL mode)
   stored in the RP2040 boot ROM. It can also be
   used by user code, to access an external USB device or host.
   So the RP2040 is doing the job of the USB2Serial converter (CH340,
   CP2102, etc..)
   When the pico is plugged to a Linux host does a /dev/ttyUSB0 come up?

   add input of solar panel too? Second idea are simple. Make a normal

   With the new PIO (hardware state machines) almost certainly yes, at
   least concerning the camera interface.
   Camera drivers will be a bit more work, but it is certainly within the
   range of possibility.

   Talking to myself here.
   I just picked up one at Micro Center. They just got the first batch in.
   They did not even know these exist when I asked! They took 1/2 an hour
   to find it. So I was the first one to get it. I paid only $1.99USD
   discounted from $4USD.
   Better get learning.

   Hoover Dam! Very interesting indeed. And for $4? It is amazing! It
   opens the possibilities and future of the R-Pi system and peripherals.
   Using MicroPython will ease programming the device as programs for the
   R-Pi can be easily ported over to this R-Pi Pico system. The future is
   looking bright… Just got to wait for the sun to rise from this dismal

   Not, in fact, fake news. That price is for the board bundled with a USB
   cable, and the same seller has the board on its own for substantially
   less
   ([390]https://classroomeshop.com/products/raspberry-pi-pico-board-only)
   , equating to around $5 US. The extra dollar is likely to be local
   taxes; while I have no idea what sales or import taxes apply in Hong
   Kong, a retail price like this, equivalent to $4 US plus a bit extra
   for local taxes, is exactly what I’d expect to see (and is what I am in
   fact seeing from our excellent UK Raspberry Pi Approved Resellers).

   As Eben has said elsewhere, we’re not surprised to see resellers
   imposing a one-unit limit at the moment, to avoid scalping, and that is
   rightly their own decision. I imagine that once the excitement has died
   down it will be easier to get hold of larger quantities.

   Basic interpolations require quite a number of operations, including
   multiplies and divides. These take a lot of instructions and therefor
   CPU time, so having a bit of HW to do it means you can tell the
   interpolators to do its work, then grab the result without having to
   use any processor cycles to do it. That can be a massive saving in
   processor time. And the these blocks are a little more sophisticated
   than a basic interpolator so the savings can be even higher. for more
   complex operations.

   Wow, I did NOT see that coming! This is quite a step in a new direction
   – very exciting. I really REALLY hope that we’ll see a BT/WiFi-enabled
   version of the pico that will sell in the $5 range; that would compete
   with the ESP8266/ESP32 boards that are becoming ubiquitous these days.
   The ESP boards are great, but sourcing them at a reasonable price can
   get really skeevy – there are counterfeits and poor quality-control
   versions of these and it can be hard to know in advance what you’re
   getting (not to mention shipping times of weeks or even months from
   China). I would much rather get a Pi Pico W from a reliable source, and
   impeccably documented like what you’ve done so far (yes I did see that
   the Arduino folks will be producing a wireless module for this, but we
   don’t know what the price will be).

   Along those lines, I’d love to see the Pi Zero W become the baseline
   model at $5 dollars, and maybe just make the original Zero available on
   a legacy basis. As long as power is available, the Zero W is a
   compelling choice for most hobbyist-level projects, given its form
   factor and the familiarity of the RasPi environment (and the community
   support that goes with it).

   When you start thinking about version two.. I would like to make an
   impassioned plea that you include a ADLC serial data link.
   Being able to network these on something simpler than ethernet but more
   sophisticated than the likes of the 8051s 9 bit serial mode would be
   really interesting and it’s not a feature that any other
   microcontroller has as far as I know. The venerable MC68B54 is the sort
   of thing. Compatibility with this would also keep the fans of Econet

   I am having some difficulty wrapping my brain around the flash
   interface. For a 32-bit wide architecture, XIP over QSPI, itself
   running at a maximum of (is it?) half the processor clock speed will be
   very slow. I thought maybe the QSPI/XIP interface would be sped up into
   the GHz range, but no. Yes the cache will help, but at best it adds
   only another 8k of full speed memory, once loaded. In other words, you
   would use XIP instructions only for background processes having no
   real-time constraints. Real-time processes – and their data – will have
   to live in the on-chip RAM (or at worst that plus 8k). Yes? No?

   How about a Raspberry Pi 4B with an RP2040 built in and more pins ;).
   Also, the PIO is really really cool, would have been great for stepper
   motor control for student robotics, had an arduino controlling 4 wheels
   and had to work around timing loops to get it to bitbang them
   successfully whereas with this you can just set one SM per wheel and
   even have them all sharing the same few instructions.

   Surely an RP2040 HAT is the next product? Instead of developing yet

   Hi, congratulations on another great product.
   I read the spec on the RP2040 and perhaps half understood :-) It
   mentions that the clock uses a PLL, does that mean the 2040 clock could
   be syncronised to an external source with a variable frequency or have
   I missunderstood?

   There are a couple of clock options, you can use the internal ring
   oscillator (ROSC) clock, or attach an external crystal clock (XOSC).
   XOSC is much more accurate, so if you need decent timing you should use
   a crystal. Once started, you should not vary the external clock as that
   will upset any timers etc as they are based on a set clock speed.
