I am modifying Chief Delphi Team#47 IR Board to accept separate power from robot distribution board (2 wires, +12 V and ground). As such, we will be gluing a small, two pin, connector to the board. Between the new connector and the existing 10 pin connector pins for power (pins 1 & 2), we will be soldering an inline 1N4007 diode for reverse battery protection. The new connector will also have add a small wire from the ground to ground (pins 3 & 4). Since the system will be connected to the 12V system, the 0.7 volt diode drop will not be an issue.
I will try to post a digital picture after the work is completed.
I haven't decided what to do yet about the 4 signals that need to come from the IR board to robot controller( 2 Pwm wires, one with 3 signals, the other with one signal and ground OR 4 PWM wires, one for each signal/ground).
