that would be my handy work for the PCB. It was made to hold the 22uh choke that has been recommended for DCS signal when the TIU is used in passive mode. Of course it’s all rated for a full 20A (welding power to some people)
This second Rev I wasn’t impressed with the banana jacks and found some through hole terminals for a decent price and then also soldered the 33.3V TVS diode to the PCB.
