USB operation

The baseboard can also be powered through two USB cables, as shown in Figure 9. It is also possible to use a
single USB cable for operation. However, single USB operation depends on the overall power consumption of
the baseboard and the radar shield attached to it. The battery manager is connected to the battery and,
depending on the current supplied by the USBs, charges the battery.
