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; however only wireless LAN is software-supported at launch.
A Raspberry Pi Pico WH version, with a 40-way header pre-soldered, is also available which has a slightly different board layout (select the WH option above to see the board).
