I wanted to take a look at the firmware of my #BINCL - binary coded decimal 10mm LED clock to get rid of the pcbs I still have from the first batch. I quickly ran into the problem of having only 5V usbasp modules or my version one board with pogo pins, able to talk to 3v3 devices, but not power them. In this revision I've added a AP2112K and a second switch, changed the usb plug and made it a single side pcb. The edge connector is inverted from before and will now hold an ISP6 port instead of the pogo pins!
Boards aren't routed yet, price in a size like this on OSHpark for 3 boards is
