When the AC power source is removed, the UPS keeps supplying the power to the ODROID-M1S boards with the battery.
The M1S-UPS has a USB serial port(ttyACM) to communicate with so that it can trigger the shutdown process by sending a low battery warning.
It will significantly reduce the risk of data loss by sudden power loss.
When the AC power source becomes available again, the UPS will supply power to the ODROID-M1S again and trigger a power-on event automatically.
