Raspberry Pi Pico W

by Raspberry Pi

A low cost, flexible microcontroller board with wireless, built around Raspberry Pi's RP2040 chip.

Raspberry Pi Pico W is Raspberry Pi's first wireless microcontroller board, designed especially for physical computing. Microcontrollers are a different type of device than Single Board Computers (like the Raspberry Pi 4 and previous generations of Pi), they don't run an operating system and they are typically programmed to do just one task - though that task can be pretty intricate and exciting! They're perfect for experimenting with hardware and using as the brains of custom devices, machines and inventions. With the onboard 2.4GHz wireless capabilities of the Pico W, it's now possible for your creations to talk to each other, and to the internet!

Apart from the addition of wireless networking, Raspberry Pi Pico W is very similar to Raspberry Pi Pico and, like all RP2040-based boards, can be easily reprogrammed over USB from a Raspberry Pi or other computer using the C/C++ SDK or the official MicroPython port. The documentation landing page is the best place to get started, or scroll down for links to the technical documentation for both the Raspberry Pi Pico W microcontroller board and the RP2040 microcontroller chip.

As standard, Raspberry Pi Pico W comes without header pins so you'll need to pick some up separately if you're planning on plugging your Pico into into a breadboard or one of our Pico add-ons. Alternatively, you can now pick up a Raspberry Pi Pico WH which comes with pre-soldered headers, and a convenient connector for solderless software debugging.

Board Specifications

Raspberry Pi Pico W has been designed to be a low cost yet flexible development platform for RP2040, with a 2.4GHz wireless interface and the following key features:

  • RP2040 microcontroller chip designed by Raspberry Pi in the United Kingdom
  • Dual-core ARM Cortex M0+ processor, flexible clock running up to 133 MHz
  • 264kB of SRAM, and 2MB of on-board Flash memory
  • On-board single-band 2.4GHz wireless interfaces (802.11n)
  • Castellated module allows soldering direct to carrier boards
  • USB 1.1 Host and Device support
  • Low-power sleep and dormant modes
  • Drag & drop programming using mass storage over USB
  • 26 multi-function GPIO pins
  • 2×SPI, 2×I2C, 2×UART, 3×12-bit ADC, 16×controllable PWM channels
  • Accurate clock and timer on-chip
  • Temperature sensor
  • Accelerated floating point libraries on-chip
  • 8×Programmable IO (PIO) state machines for custom peripheral support

Raspberry Pi Pico W and Pico WH incorporate an Infineon CYW43439 wireless chip. CYW43439 supports IEEE 802.11 b/g/n wireless LAN, and Bluetooth 5.2.

Documentation

All documentation for the Raspberry Pi Pico W board and the RP2040 microcontroller can be found through the documentation landing page.

The API level Doxygen documentation for the Raspberry Pi Pico C/C++ SDK is available as a micro-site.

Helpful microcontroller to use with the Pico Display pack. Does everything i need it to.

Brilliant device, not quite as fast as a Teensy but better price and more pinouts!

Great little device, very affordable with a really small footprint. Works perfectly for my project, powering a framed pico paper display.

A wonderful little device, and so cheap it's worth having a few kicking around so you can just act on ideas.

I have several Pi Pico boards with and without headers, but I thought I would try out the WH and save myself some soldering. It fits nicely in a breadboard and the little debug header is soooo cute!

I am using this for building a rain guage. I am very pleased that you can turn it into a Modbus slave using TCP IP in Micro Python and get the data off Wirelessly.

Haven't had any problems so far. The bluetooth and wifi works great as well. The test programs supplied by on the raspberry pi website worked.

Bought the first Pico W for a mesh radio project. The second to get back into 'electronics' and enjoying just having fun. Think I need a Pi 5 now to replace my ageing Apple computers. Good technology and understanding flows from just trying stuff out.

Bought a load of bits for a few projects I wanted to start but unfortunately broke my hand in between ordering and delivery. 😩 So I haven't yet started on the projects I ordered them for. Bought to have a go with turning it into a retro games emulator. As for delivery, it was fast and well packaged and I will certainly order more bits as with all this spare time I have at the moment, I'm coming up with plenty of new ideas.... Maybe a robotic hand incase mine never heals.

One of the better microcontrollers with Wi-Fi. I’m not overly thrilled with micropython, it’s ok but feels like WIP for some features - documentation needs a lot more effort. May give circuit python a go. In any case the pico W itself is a great unit. A little limited on storage space for some of the adafruit bloat libraries, power save modes limited in micropython (fixes are available with google searching), otherwise grand.

really great device. I use it with https://github.com/earlephilhower/arduino-pico . programming it can be sometimes a bit frustrating with macs -- I use a usb-c adapter, which might make things more complicated, and I have to unplug and plug it back in quite often when programming it. but when it works, it works. uploading new programs to it is definitely fast. great device

A tiny microcontroller with network access and programmable in Rust? What more could you want?

hopeing to use this with the Kitronik Autonomous Robotics Platform, to make a wirelessly controlable robot :) Also loving the micropython API for network comms.

Used a few of these for different projects always found them top quality and great support from Pimoroni and the Pi community.

Actually purchased one of these along with a WH version, also some pi debug probes. A great combo. Especially like that the integration of Pico WH + probe+platformIO is really good.

Great little machines, I am using them as a Socket based co-processor to provide Analogue and I2C capabilities for a Pi Zero 2 running VFX Forth.So far it is looking really promising. I got the H version as alas failing eye sight has robbed me of the ability to solder the pins on myself.

As ever, the RPi Pico W is great news for micrcontroller users. I used this one with Microblocks.fun to read the cheerlights colour and produce Neopixel colour patterns.

Really really good, it is brilliant for beginners to learn simple programming and amazing for anything above that.
