chordata

everything you need to build a Eurorack module around a microcontroller. an RP2040-based development board with a 10-pin Eurorack power header and 3.3V voltage regulator broken out to header pins, lots of GPIO, and a reset button.

all SMD parts are pre-soldered. to assemble Chordata, there's about 15 minutes of THT soldering to do for the headers, power connector, and USB Type-C port (these parts are all included). the USB port has a very small 0.85mm pin pitch, but is straightforward to solder with flux and patience; however, this isn't recommended as a beginner project.
