DosTres_Automation_Controller
The DosTres Automation Controller is a shield for the Arduino Uno that allows you to control a number of high power devices. It carries motor drivers to power 2 brush DC motors at 40v/5A as well as 3 MOSFET load switches to control high load devices (solenoids, lights, pumps, etc.). The DosTres also allows you to drive a stepper motor in place of the DC motors. The Eagle files for this board can be found here.
