One of the coolest things that came with the release of the Raspberry Pi Pico was making the RP2040 (and recently RP2350) microprocessors available for purchase. Makers get incredibly creative with implementing this processor into their projects, and today, we've got an excellent example to share of just that. The masterminds behind Ploopy Co have assembled an RP2040-powered trackpad they call the Ploopy Trackpad.
The Ploopy team decided to make this project totally open source, which means you can access all of the build files and software to recreate it or modify it yourself at home. But if you don't feel like 3D printing, ordering a PCB, and programming it yourself, you can always buy one pre-made for $94 at the Ploopy website. Alternatively, you can meet somewhere in the middle and order a kit to assemble yourself for about $72.
