# Laser4DIY TEC Controller

![alt text](hardware/finalboard.jpg "TEC Controller board")

This is the repository for the TEC (Thermo Electrical Cooling) controller used in the [Laser4DIY project](http://www.laser4diy.org/).

## Specs

* Designed as a shield for the Arduino Due
* 2-channel TEC controller, driving peltier elements up to 106W heat transfer capacity per channel (12A at 15.5V)
* 2 boards can be stacked for a 4-channel TEC controller, driven by a single Arduino Due
