The Raspberry Pi Backup Battery Hat V1.2 is an advanced uninterruptible power supply for the Raspberry Pi that adds an innovative power back-up functionality and development features to the innovative microcomputer!
Because of without any battery on standard UPS , Users need to equip with a LiPO battery by themselves. Meanwhile, this can be easily upgraded to the extended 3000mAh version if you like, which enables prolonged use of a Raspberry Pi without a power supply connected!
The Raspberry Pi Backup Battery Hat V1.2 features an embedded measurement system that continuously checks the powering voltage of the Raspberry Pi. When the cable power on the Raspberry Pi is absent or insufficient, or the device detects a power failure, the Raspberry Pi Backup Battery Hat V1.2 automatically switches to the unit’s battery source. The module then continues to check the voltage on the Pi and switches automatically back to the regular cable supply, , when power is once again available.At the same time, the battery will be charged, if its voltage is lower .
Raspberry Pi Backup Battery Hat V1.2 is equipped with plenty of features which make it an extremely useful tool for Raspberry Pi project development. It not only provides powering continuity, but also offers extra functions. These extra features result in the UPS being a superior all-in-one device perfect for many innovative projects and embedded applications.
