# Orbit
![Orbit](https://raw.githubusercontent.com/ai03-2725/Orbit/master/Images/PCB-R2.0.jpg)
A split ergonomic keyboard project.
Keyboard Maintainer: [ai03](https://github.com/ai03-2725)
Hardware Supported: The [Orbit PCB](https://github.com/ai03-2725/Orbit)
Hardware Availability: [This repository](https://github.com/ai03-2725/Orbit) has PCB files. Case group buy orders are currently closed.
Make example for this keyboard (after setting up your build environment):
make ai03/orbit:default
See the [build environment setup](https://docs.qmk.fm/#/getting_started_build_tools) and the [make instructions](https://docs.qmk.fm/#/getting_started_make_guide) for more information. Brand new to QMK? Start with our [Complete Newbs Guide](https://docs.qmk.fm/#/newbs).
