Note that when the dev kit is powered from the battery only, the following carrier board features are non-
function – the USB host ports, Ethernet port.
When a battery is not in use, the SMB1357 battery charger U3300 supplies power from the 12V input to the
SOM.
3.9.6 Debug Serial UART over USB J2700
Figure 13 J2700 Debug UART over USB
The UART connection used on the Open-Q 2100 SOM is a USB micro B connector (J2700). 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.
