UPS2-U3 [0093]


This item is out of stock

Uninterruptible power supply (and battery backup) designed specifically for the ODROID-U3.

An Uninterruptible Power Supply is an electrical apparatus that provides emergency power to a load when the input power source, typically mains power, fails. The on-battery runtime of most uninterruptible power sources is relatively short, but in this case it is more than sufficient to start a standby power source or properly shut down the ODROID-U3.

It is equipped with a rechargeable 3,000mAh Lithium Polymer battery and a charging circuit with a booster IC for 5V output.

When the AC power source fails, the UPS2 keeps supplying the power to the ODROID-U3 with the battery. There is a digital output pin to inform the ODROID-U3 of a battery low-level warning which can trigger the shutdown process. Once the AC power source resumes, the UPS2 will supply power to the ODROID-U3 again automatically.
