This repository contains the KiCad files for a pair of MIDI breakout boards. There isn't anything particularly special about them, besides perhaps the fact that the MIDI OUT has a switch to select between 3.3V and 5V operation, as well as two BS170 MOSFETs to sink the current, rather than using buffer chips. Oh, and we use JST-XH connectors, because I hate those loose "DuPont" headers that allow you to plug things in the wrong way around! >:(
