3.7.8 Debug Serial UART over USB J1500 (12)

The UART connection used on the Open-Q 865XR is a USB micro B connector (J1500). This debug
UART is available over USB via the FTDI FT232RQ chip on the carrier board. To get the serial terminal
working with a PC, user needs to ensure that the appropriate FTDI drivers are installed. Use latest FTDI
drivers from https://www.ftdichip.com/FTDrivers.htm
the location of J1500 on the carrier board.

3.7.9 Optional Debug UART Header J1501 (9)

The UART connection used on the Open-Q 865XR is a UART header (J1501). This is an optional debug
header. This debug header and J1500 should not be used at the same time. The following table
describes the pinout of the debug UART header. This debug UART is available over USB via the USB to
TTL Serial 1.8V cable. To get the serial terminal working with a PC. See item 9 in Figure 1 for the location
of J1501 on the carrier board.

USB 3.1 Type C (for ADB) J2200 (11)

The Open-Q 865XR carrier board contains one USB 3.1 Type C connection (J2200). This connection is
used for Android debug bridge (ADB) functionality. To get the adb shell, ensure that the board is up and
running and connect the Type C cable between the board and the PC. Type the command adb root and
