Raspberry Pi Pico WH

The Raspberry Pi Pico WH is the header-ready version of the Pico W — featuring the same RP2040 microcontroller and Infineon CYW43439 wireless chip, but with male headers pre-soldered to all through-hole pads for immediate breadboard use.

The CYW43439 provides Wi-Fi (802.11 b/g/n) and Bluetooth 5.2 (Classic + BLE) connectivity. The RP2040 offers a dual-core Arm Cortex-M0+ processor running up to 133 MHz, 264 KB SRAM, 2 MB flash, and a rich set of I/O including 26 GPIO pins, SPI, I2C, UART, ADC, and 8 programmable I/O (PIO) state machines.
