I purchased the DROK® AC 110V/220V to DC 12V/5V 3A LCD Dual Voltage Power Supply Module Board Universal Power Supply Adapters For 15-22 inch LCD Display from your Amazon store. I am building a prototype for now. Can you give me the name/spec of the 7-pin connector you use for output? I plan to have custom cables made, but need the name of that connector to build them.
