4 throttles so 4 independent DCC locos can run here. Still pending are the direction and emergency stop switches. An Arduino Mega produces the DCC signal. Power comes from two PC power sources wired in series for 12V+3.3V = 15.3V: Regards, Robert
Cool, Similar to the miniDCC project I built. It to has 4 independent throttles, plus turnout control routing and LCD.
