Raspberry Pi Pico W

The Raspberry Pi Pico W adds wireless connectivity to the popular Pico platform. Built around the RP2040 microcontroller with an Infineon CYW43439 wireless chip, it supports 2.4GHz Wi-Fi (802.11 b/g/n) and Bluetooth 5.2, enabling IoT projects and connected devices.

Maintaining the same compact form factor and pin layout as the standard Pico, the Pico W is ideal for projects requiring network connectivity without sacrificing the flexibility and performance that made the original Pico popular.
