Our own uninterruptible power source for the Raspberry Pi!
The UPS hat is powerful enough to continuously deliver 3 Amps of current to the Raspberry Pi, with an Ultra lower power STM32 controller to make the Raspberry Pi last longer when powered with the battery. The Hat also includes a real time clock (DS3231), which can easily be accessed using the I²C pins on the Pi. It is compatible with models of the Raspberry Pi that have a 40 pin GPIO header, up to the Pi 4! Additional space and holes on the board can be used to secure the more powerful 18650 battery which offers longer run time. The whole assembly can easily fit inside our HighPi cases. Extra long headers are used to mount other hats on top of the UPS Hat.
The control code (see User Guide) powers the Pi down after a set number of minutes. Once power to the Pi is re-established, the Pi restarts automatically. Approximate run times for the two battery options are;
- Included 450mAh battery: 10-30 minutes
- Optional 18650 battery: 30 minutes - a few hours
Included
- UPS HAT
- 3.7V 450mah Li-Ion rechargeable battery with XHP-2 connector
