Pico WH RP2040 Development Board

The WaveShare Pico WH is a microcontroller board built around the RP2040 dual-core Arm Cortex-M0+ processor running up to 133 MHz. It targets makers and engineers who need integrated wireless connectivity for IoT prototypes or embedded control projects. The board arrives with a pre-soldered header for immediate breadboard use.

Wireless Thermals and Power

The onboard Infineon CYW43439 chip provides Wi-Fi 4 on 2.4 and 5 GHz bands without an external antenna module. Wireless operation adds only modest current draw to the dual-core processor baseline. The compact layout has no active cooling, so thermal output stays low during typical sensor or network tasks.

SDK and Header Benefits

The pre-soldered 26-pin GPIO header removes the need for manual soldering and speeds up hardware iteration. Official C/C++ and MicroPython SDKs include peripheral drivers and wireless stack examples. Tutorials and reference designs reduce bring-up time for both beginners and experienced developers.

Questions about this item

How do I solder the pre-soldered header onto the Pico WH without bridging the 26 GPIO pins?

The header is already soldered; simply press the board into a breadboard or socket. The step people get wrong is applying heat again, which can bridge adjacent pins or damage the CYW43439 wireless chip.

Will the onboard Infineon CYW43439 wireless chip need replacement after extended Wi-Fi 4 use?

The CYW43439 is a surface-mount component rated for the product lifetime; no user replacement is expected. Keep the antenna area clear of metal and avoid electrostatic discharge during handling.

At what point does the dual-core Arm Cortex M0+ processor throttle under sustained 133 MHz workloads?

The RP2040 has no active cooling, so prolonged 133 MHz operation can raise die temperature until the chip reduces clock speed. Adding a small heatsink or reducing duty cycle delays throttling.
