Hi @uchiha, welcome to the forum 
Electrical connections need to be made, but they’re direct connections so there’s no special PCB that’s required, just wires or a connector. Generally our vehicle electronics are set up on an electronics tray, which we offer a set of terminal blocks for, to make it easier to connect to the power supply and thrusters.
You can get those terminal blocks if you want, but if you’re using fewer connections then you may wish to get a similar set directly from an electronics supplier, without as many connection slots (just mind the current rating)
