The controller also display the name, value and package of that component.

Mount File Inputs: 

The mount file contains the following data and the controller reads this file line by line and generates the following outputs.

Power Inputs:

This device requires 12V DC power and around 1 amps current. There are two voltage regulators 5V and 3.3V for the on board peripherals. In order for the cables not to disturb the user, the power is transferred to the board with a small slip ring.

Outputs:
