Good news is I completed a 4.2.4 and it works perfectly! Even did the SMT components myself. Bad news is I burned up my trusty 4.0. I was trying to put an RJ45 jack in place of the separate servo/blower connections. I had done the servo mod a long time ago and it has always worked fine so I had the correct wire locations. The only thing I can think of is that since the 4.2.4 shares a ground between the blower and servo I thought I could do the same with the 4.0 and used the blower ground for both blower and servo. When plugged in it worked wonky for a while, the blower would never turn off, then quit all together. The rPi now gets very hot in one spot and the whole heatermeter is dead. I wanted the RJ45 jack output so I could use the 4.0 and 4.2.4 interchangeably. Solder points looked fine so ground is only thing I can think of. So the question is would the shared ground on the 4.0 be the problem? I, of course, know nothing of electronics. Thanks. Dan
