3.7.18 Audio Outputs Expansion Header J1901 (32)
The Audio Outputs Expansion Header J1901 (32) provides two differential and two single ended line outputs,
earpiece amplifier, one codec PDM 1-bit interface, and some GPIO signals to implement any required custom
logic. The carrier board rails 1.8V, 3.3V, 5.0V and 12V are also exposed. The connector pinout is shown in
next table.
