- 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.
- Pin no. 6 should be connected to GND and pin no. 9 should be connected to V3.
It should be noticed, that the LPC debug holes on apu board are much smaller, so regular pin header will not fit there.
