Headset Jack J1501 - Intrinsyc Open-Q 670 HDK User Manual

Open-Q™ 670 HDK Hardware Development Kit User Guide Version 1.0
The NFC expansion header provides a 20 pin connector for attaching an optional NFC
board. This header also allows user to connect to the free GPIOs and I2C lines when
NFC is not used; therefore, enabling other use cases. Please refer to Table below for
detailed information regarding the signals that are being brought out by this connector.
