4 (LAD1) 5
5 (LAD0) 3
6 (GND) 2, 4, 6, 8, 10, 12, 17
7 (LPCRST) 13

9 (V3) 18

TPM1a

  • At least one pin of no. 2, 4, 6, 8, 10, 12 and 17 should be connected to GND and pin no. 18 should be connected to V3.
  • Pins no. 14, 15, 16, 19 and 20 stay unconnected.

APU3/4

  • Pin no. 6 should be connected to GND and pin no. 9 should be connected to V3.

Important!

It should be noticed, that the LPC debug holes on apu board are much smaller, so regular pin header will not fit there.
