# 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 | ||
