The Raspberry Pi Pico WH is a compact, affordable, and versatile microcontroller development board powered by the RP2040 chip, which was designed by the Raspberry Pi Foundation and introduced in January 2021. It is well suited for learning programming with MicroPython while also offering the flexibility required for a wide range of electronics and embedded projects.
The RP2040 microcontroller is built on the Arm Cortex-M0+ architecture and was fully developed in-house by the Raspberry Pi Foundation. It provides reliable performance and efficient processing for various applications.
The Raspberry Pi Pico WH is an upgraded version of the original Pico board. It maintains the same compact form factor but adds built-in 2.4 GHz wireless connectivity, making it suitable for IoT and connected projects.
At the core of the Pico WH is the RP2040 microcontroller, which includes:
Dual Arm Cortex-M0+ cores running up to 133 MHz
264 KB of SRAM
30 GPIO pins
A wide range of interfacing options for peripherals and sensors
The Pico W and Pico WH variants include the Infineon CYW43439 wireless chip, which supports IEEE 802.11 b/g/n Wi-Fi and Bluetooth 5.2. At launch, the board primarily supports wireless LAN (Wi-Fi) connectivity.
