Raspberry Pi Pico-WH

The Raspberry Pi Pico WH is an upgraded, versatile development board built around the RP2040 microcontroller, launched by Raspberry Pi in January 2021. Compact, cost-effective, and flexible, it is ideal for learning coding with MicroPython. The RP2040 is a dual-core ARM Cortex-M0+ microcontroller, entirely designed by the Raspberry Pi Foundation.

The Pico WH introduces wireless connectivity while maintaining the same compact form factor as the original Pico. It features a 2.4GHz wireless interface via the Infineon CYW43439 chip, supporting IEEE 802.11 b/g/n Wi-Fi (Bluetooth 5.2 is present but not supported at launch).

At the heart of the board, the RP2040 provides two Cortex-M0+ cores clocked at 133 MHz, 256 KB of RAM, 30 GPIO pins, and a wide range of interfacing options. Paired with 2 MB of onboard QSPI Flash memory, the Pico WH is ready for both code and data storage.
