2023.12.19 RF363 instead of HP363:
I ordered this last month and just recently went to use it. It should be 12v input power so I connected it to 12v without looking closely. Smoke came out. Looked closer, see its marked 5v in, this is a model RF363, not HP363, and it's got a 5v->3.3v regulator on it that smoked because it can't take 12v in. I replaced the regulator but it doesn't turn on. I checked further, the 3.3v out is 0v, there's a short to ground now on the 3.3v, probably one or both of the ICs shorted. I went to just order another because I thought I was an idiot for thinking it was 12v, that's when I noticed I DID order the 12v and was sent the 5v. I've started a "wrong item received" exchange with amazon, though I don't know if they will accept the repaired board back or try to charge me for it. Please make sure you are shipping HP363 not RF363.
