While I did do some soldering last night, it ended in failure. I don't know what it is, but everything seems much bigger on the layout than real life. The 3.3V power supply board used a converter chip that was absolutely microscopic QFN while attempting to hand solder. Got it all together, no blue smoke bUT also no output. Likely one of the pins is not connected. I also had trouble soldering amy pounds on the board that were connected to the ground plane. Oh well, I'll try and de bug it, but it's just a power supply and easily replaced by something else.
