Headset Audio Jack - J27 - Intrinsyc Open-Q 212A User Manual

The sensor expansion header (J53) allows user to connect to an optional home automation connectivity
accessory board that features the Qualcomm QCA4024 Zigbee/BLE chip. Users can also use this port
to connect their own peripherals. Various low-speed buses are available on this header. Please refer to
the schematic and check power draw before connecting peripheral to this header.

3.8.11 Headset Audio Jack – J27
J27 is a standard 3.5mm TRRS jack in CTIA pinout order with headset detection support. Signals are
routed to Audio CODEC WCD9326 on the SOM. This function is not supported in BSP V1.0 and
maybe supported in the future BSP.
