Pico W

Released June 2022

Raspberry Pi Pico with 2.4GHz Wi-Fi and Bluetooth added, a microcontroller board with two 133MHz Arm Cortex-M0+ cores, 264 KB of SRAM and 2 MB of flash, for connected sensors and IoT projects rather than running Linux.

What reviewers say

Reviewers agree it adds useful Wi-Fi to the Pico at a very low price while staying compatible with existing Pico add-ons and projects, backed by good software. Tom's Hardware criticised the micro USB port, lack of a reset button and no Bluetooth support at launch; Jeff Geerling measured modest Wi-Fi speeds and noted it needs its own firmware.
