In the electronics world, a small one inch square board with serrated edges makes it easy to add many circuits in a small area. You can grab a pre-filled module, throw it on your PCB of choice and save yourself a lot of time routing and soldering. This tiny Raspberry Pi 2040 module from [SolderParty] ticks all those boxes.
With all 30 broken-out GPIOs, 8MB of built-in flash, and a NeoPixel on board, you’ll have plenty to play with on top of the RPi2040’s already impressive specs. Gone are the days of in-circuit programmers, and it uses a UF2 bootloader to make it easy to transfer new images over USB. Rust, MicroPython, Arduino, and the PicoSDK are all code development options. All KiCad files, BOMs, schematics and firmware are on GitHub under a CERN license for your perusal pleasure. They’ve conveniently included footprints and a reference carrier board design.
It’s a handy little project that might be good to keep in mind or just use as a reference design for your efforts. We have a good overview of the RPi2040 from an STM perspective. If you are curious what you could use this stamp for, why not control an HDMI signal?
