	[[File:LPR-PCB-v1.png\|left]] The prototype PCB worked as designed. However the traces were insufficient to carry the current required. The new relays are rated at 12 amps @ 12vdc. The original 40 amp relays are overkill for the fiver, and ~~these relays should suffice~~.		[[File:LPR-PCB-v1.png\|left]] The prototype PCB worked as designed.

	The new PCB, shown here, features the widest traces I could fit, plus the traces are doubled; top and bottom. We will be testing the prototype with FLARE this summer. As soon as the new boards are delivered I will likely replace the prototype board with the production version.
