Guides
QMK
This board fully supports QMK, refer to the official docs.
VIA
If you wanna use VIA follow the instructions here.
Calculator
SheepyPad implements a simple calculator that you can use to perform basic math operations. Follow the Calculator Guide to get started.
PCB
Follow the PCB Assembly Instructions to build the PCB and test it out.
Repo structure
Docscontains all documentation and images for the project.Firmwarecontains both the source and precompiled binaries.Hardwarecontains the KiCad design files for the keyboard, fabrication files (in the Gerbers folder).Mechanicalscontains STEP file of the PCB and components, plate and case files.
Project status
Project is currently in development. V1 boards have been produced and tested successfully. V2 boards are in the works and will add/change currently available features (both hardware and firmware wise).
Software is in constant change and being updated on my qmk_firmware fork available here. You can find a basic default code example (with precompiled binaries) in this repo too if you want to quickly get it up and running.
