# Contra
Extremely low cost ortholinear keyboard

![Render](https://raw.githubusercontent.com/ai03-2725/Contra/master/Images/back-2.0.jpg)

The bare minimum for a functional keyboard.

#### In light of recent claims that I am 100% liable for any of my open source PCBs, I am adding this disclaimer.
#### I provide these PCBs as a reference for designing keyboard PCBs. Using them within your projects will require a will to do research of one's own and to learn the workings of them, potentially fixing issues if they exist.
# I provide these PCBs without liability and without any guarantees regarding functionality, as expressed in the MIT license under which all of these PCBs are licensed.

### Features
- 2U or split space.
- All through-hole parts. 48x diodes, 1x Pro Micro.
- Assembled by M2 standoffs and screws.
- Programmable via firmware of choice, such as TMK.
