Add back up power to your U3 board!
The ODROID-UPS3 (Uninterrupted Power Supply) device is designed specifically for the ODROID-C1,C1+ and ODROID-C2.
It is equipped with a rechargeable Lithium-Polymer Battery, Charger IC and 5Volt Boost DCDC.
When the AC power source is removed, the UPS3 keeps supplying the power to the ODROID boards with the battery.
There is a digital output pin to send the battery low-level warning to the ODROID to trigger the shutdown process.
It will significantly reduce the risk of data loss by sudden power loss.
When the AC power source becomes available again, the UPS3 will supply power to the ODROID again automatically.
