RP2040 Stamp

The RP2040 Stamp packs the full power of the Raspberry Pi RP2040 into a tiny 1×1 inch module designed for embedding in your own PCB designs. With castellated edges at 2mm pitch, it's easy to hand-solder onto your custom boards—no reflow oven required.

Beyond the RP2040 chip, this module integrates 8MB of flash, a 500mA voltage regulator, LiPo battery charging, and even a Neopixel LED—everything you need for a complete embedded system in a compact package.
