DESCRIPTION
The Raspberry Pi Uninterruptible Power Supply (UPS) is designed to provide continuous and reliable power to the Raspberry Pi in the event of a mains power failure or disruption. This compact and efficient UPS solution ensures that the Raspberry Pi remains operational and data integrity is preserved even during power outages.
The Raspberry Pi UPS uses 2 standard-length flat-head 18650 batteries for power supply. It supports charging and discharging at the same time, ensuring you can continue using the Raspberry Pi while charging the UPS. It also integrates a fuel gauge chip MAX17040G for 5V 3A, and INA219 for 5V 5A, which can be used to measure battery voltage and remaining power.
For UPS 5V 3A, when the lithium battery is fully charged, all five green power indicators will light up, indicating that the battery is fully charged. The battery capacity indicated by the five power indicators are 20%, 40%, 60%, 80%, and 100%. In addition, the Raspberry Pi UPS has a power adapter plug-in detection function. When the power is plugged in, Pi 107 (BCM number IO4) will detect a high level, and when it is unplugged, it will be a low level. To enable this function, you need to short-circuit the two soldering pads on the back of the UPS.
The UPS is connected to the Raspberry Pi via spring pogo pins, installed at the bottom of the Raspberry Pi.
How to select UPS:
- For Raspberry Pi Zero, Raspberry Pi 3, and Raspberry Pi 4, use UPS 5V 3A
- For Raspberry Pi 5, use UPS 5V 5A
