Following the hugely popular Raspberry Pi Pico, the new Raspberry Pi Pico W is a wireless-enabled version of the RP2040-based board, adding 2.4GHz 802.11n WiFi connectivity!

The addition of wireless connectivity opens up the Pico W to a vast new range of projects such as remote sensor readings, remote control, home automation, mini web servers, wireless GPIO pin control and much, much more!

At the heart of the Pico W is the RP2040 – the same chip used in the original Raspberry Pi Pico, featuring two ARM Cortex-M0+ cores clocked at 133MHz; 256KB RAM; 30 GPIO pins; and a broad range of interfacing options. This is paired with 2MB of onboard QSPI Flash memory for code and data storage.

WiFi is enabled via the use of an Infineon CYW43439 wireless chip. The CYW43439 supports IEEE 802.11 b/g/n wireless LAN, and Bluetooth 5.2.

With the same footprint and same RP2040 chip, this WiFi Pico can be used as a drop-in replacement for your existing Raspberry Pi Pico projects, upgrading them with WiFi. Just grab a Micro-USB cable (or our handy Pico Essential Kit with a USB cable, headers and more!), install the latest MicroPython Pico W specific U2F file and start programming!

The Pico W can be quickly and easily programmed using MicroPython and C/C++* using popular editors such as Thonny. Learning how to use the Pico and MicroPython is also very easy thanks to the dedicated Getting Started projects and guide. There's also a guide for connecting to the internet with the Raspberry Pi Pico W.

*Initially, Wi-Fi connectivity will be supported by MicroPython only.

The main chip on board is the RP2040 made by Raspberry Pi (their first in-house microcontroller chip!) and is a dual-core ARM Cortex M0+ processor, with a flexible clock running up to 133MHz. WiFi is enabled via the use of an Infineon CYW43439.

A few RP2040 GPIO pins are used for internal board functions:

  • GPIO29 OP/IP wireless SPI CLK/ADC mode (ADC3) to measure VSYS/3
  • GPIO25 OP wireless SPI CS - when high also enables GPIO29 ADC pin to read VSYS
  • GPIO24 OP/IP wireless SPI data/IRQ
  • GPIO23 OP wireless power on signal
  • WL_GPIO2 IP VBUS sense - high if VBUS is present, else low
  • WL_GPIO1 OP controls the on-board SMPS power save pin (Section 3.4)
  • WL_GPIO0 OP connected to user LED


Apart from GPIO and ground pins, there are seven other pins on the main 40-pin interface:

  • PIN40 VBUS
  • PIN39 VSYS
  • PIN37 3V3_EN
  • PIN36 3V3
  • PIN35 ADC_VREF
  • PIN33 AGND
  • PIN30 RUN
