PROJECT HAS BEEN UPDATED TO KICAD V5.0!
The schematic will require some custom parts that can be found in our other repository RPi_CM3_Parts. The schematic contains everything required to get the CM3L to run. The rest of the pins are free to be used for any project. These files are meant to help jumpstart a project that wants to build around the CM3L.

Questions
How big is the Pi Compute-3-Lite MT32 PCB?
It measures 76.2 × 104.1 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Pi Compute-3-Lite MT32 use?
70 parts, built around the H11L1 and PCM5102PW. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the Pi Compute-3-Lite MT32 KiCad files?
From the peon374/mt32-cm3plus repository on GitHub, at the commit this page was made from: the board is hardware/Pi-Compute-3-Lite_MT32.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Pi Compute-3-Lite MT32 design in my own project?
Its repository states no licence, so its author keeps all rights: ask peon374 before reusing the design.
