Raspberry Pi Pico WH is a microcontroller board based on the Raspberry Pi RP2040 microcontroller chip.

The RP2040 microcontroller chip ('Raspberry Silicon') offers a dual-core ARM Cortex-M0+ processor (133 MHz), 256 KB RAM, 30 GPIO pins, and many other interface options. In addition, there is 2 MB of on-board QSPI flash memory for code and data storage.

Raspberry Pi Pico WH has been designed to be a low cost yet flexible development platform for RP2040 with a 2.4 GHz wireless interface using an Infineon CYW43439. The wireless interface is connected via SPI to the RP2040.
