For more details regarding configuring the GPIOs on this header, refer to the Open-Q 865XR SOM
Software Release Notes to determine feature support in the latest software release.
Special Notes:
•
GPIO_15_RADAR_INT (pin 6) is shared with the Boot LED (see section 3.7.7) on the
development kit. In order to use GPIO_15 on the sensor header, R2409 should be removed and
software changes are needed to remove the boot LED functionality. See R-3 schematics for
details.
3.7.19 Audio Inputs Expansion Header J1800 (27)
The Open-Q 865XR SOM Development Kit audio subsystem is built around the Qualcomm Audio Codec
WCD9385 (28). The Audio Inputs Expansion Header J1800 exposes some of the audio input capabilities
of WCD9385 for the user. See item 27 in Figure 1 for the carrier board location of this header. The pinout
for this header is shown in the table below.
