I built my own pcb to run a 328. This is really a continued test of learning ki-cad. All the ki-cad part footprints were accurate. Initial testing of the power regulator was positive (pun intended). I will do an ISP test soon. There is no USB chip on the board, as its really a footprint prototype. It does require an Atmel ISP to program. I did hand solder all the surface mount chips. The gunk around the MCU is flux.
