Table 17 above shows the pin assignments for the CPU board version 2.
Note that pins 13 and 15 have 4.7K pullup resistors to +3.3V on the v2 CPU board.
7.3.7
Analog Audio I/O
This header contains the input and output analog audio signals. It is intended to provide a path for a
differential microphone input and one single ended line level output.
The Analog Audio I/O connector mates with J31 in the I/O Jacks PCB.
