2 layer board of 1.06x0.39 inches (26.90x9.93 mm). ISP single in line 6-pin pogo adapter for AVRs. This updated version fixes a drill size issue and puts pin numbers on the silkscreen. It also makes it clearer that pins 2 and 6 should be slightly longer so as to make contact first. These two pins (VCC and GND) hit the alignment vias on the target board.
