adb shell on the PC prompt to exercise the adb shell functionality. While ADB utilizes only the high-speed
channel, this USB type C connector supports the USB 3.1 specification including the super speed data
channel. This USB connection is also uses as the charge source when the dev kit is powered by a battery

USB 3.1 Type A Connector J2300 (5)
The Open-Q 865XR carrier board contains one USB Type A connector J2300 situated on the north side
of carrier board, which exposes USB 3.1 host functionality. This USB connection is designed to provide
up to 1A VBUS current for external devices. See item 5 in Figure 1 for the location of J2300 on the carrier
board.
If the user intends to use a M.2 PCIe card on the dev kit that requires a USB connection (see 3.7.15
below), then the M.2 PCIe USB enable DIP switch S2301 (6) must be switched to closed / ON (figure
