Pico RP2040 board for embedded projects

This WaveShare board packages the Raspberry Pi Pico RP2040 microcontroller with a yellow pre-soldered header for immediate breadboard use. It delivers a dual-core ARM Cortex M0+ processor running up to 133 MHz, 264 KB of SRAM and 2 MB of on-board flash memory. The module includes 26 multi-function GPIO pins and castellated edges for direct carrier-board soldering.

Upgrade from bare modules or headerless units

The pre-soldered header removes the need for manual soldering, saving assembly time and reducing the risk of cold joints on prototype builds. It replaces bare RP2040 modules where rapid iteration on a breadboard is required. The jump is worth it when development speed matters more than the minimal cost premium over unsoldered variants.

Suits makers and engineers starting with RP2040

This board suits hobbyists, students and engineers who want a ready-to-program RP2040 platform with drag-and-drop USB mass-storage loading for C/C++ or MicroPython. Builders needing integrated wireless connectivity, higher pin counts or larger memory should evaluate alternative controller platforms.

Questions about this item

Will the 26-pin yellow header fit a standard 0.1-inch breadboard?

Yes, the 26 GPIO pins are on a 0.1-inch pitch, matching standard solderless breadboards and perfboards.

How do I put the board into programming mode for drag-and-drop flashing?

Hold the BOOTSEL button while plugging the micro-USB cable in; the board then appears as a mass-storage device for UF2 file copy.

What happens if the on-board 2 MB flash wears out from repeated reprogramming?

The flash is soldered to the module and not socketed, so the entire Pico board would need replacement.
