After procrastinating on attempting to assemble some or all of the main components on the OSH Park boards with mylar stencils and a toaster, I decided since all of the work was already done to give MacroFab a try for small quantity turn-key fabrication and assembly.

I got one assembly at a cost of approximately $70 and helped debug the part placement UI of their web-app (I put the switcher at a 30-degree angle to squeeze it in the corner and they were only handling 0/45/90 geometry at the time).

The results *look* amazing:

I measured 26k between VCC3V3 and GND - a little low but enough for me to go ahead and populate some pins on the ICSP pads and then go ahead and try to power it on.

Unfortunately, that's as far as I got today. It railed the current limit at 200mA :-(

It was late and a quick 1A current limit temp-test showed the ATmega328p to be the hot potato.

Initial debug is showing me I did some silly things with the clocks - got the footprint wrong on the ABM11 crystal for starters. Looks like XTAL1 and XTAL2 are dead shorted via pins 2 and 4 of the package - pretty sure I flipped the top and bottom views when drawing the footprint.

Next steps:

Pull Y1 (ABM11 crystal) and pull the ATmega328p RESETn to GND
- if that removes the power dissipation, next step is to try letting RESETn get pulled high
- if that works I'll try to program it and find a different crystal to maybe fit that footprint...
