Description

This is an Uninteruptible Power Supply (UPS) HAT for Raspberry Pi from WaveShare. It is able to charge the batteries and provide power output at the same time from external power supply. Automatically switch over to batteries output if external power supply is unavailable, keeps the system running without any trouble.

This HAT is compatible with:

Hardware

  • The 8.4V interface is the charge port. You can plug the 8.4V, 2A charger provided for charging the batteries.
  • WARNING LEDs are the indicators of batteries, they turn on if you reverse batteries.
  • The OFF/ON switch can be used to turn on/off the Raspberry Pi.

Note:

  • Please check the WARNING LED when you're mounting batteries, make sure that you insert both batteries in the correct way. You cannot charge batteries if they are reversed.
  • The board may not work when you mount the batteries for the first time, you need to charge batteries on board for a while to activate them.
  • Please use the charger provided, the module may be destroyed by other unsuitable power adapters/chargers. The charger is an EU type plug with 8.4V, 2A output.

Designed specifically for the Raspberry Pi Motherboard

Comes with soldered standard Raspberry Pi 40 pin GPIO header, customized for Raspberry Pi series boards. It aligns perfectly to Raspberry Pi's GPIO male header pins. Simply stack the UPS HAT on the RPi board, and you're good to go!

Real-Time Monitoring

It is able to monitor the batteries' voltage, current, power, and remaining capacity. When the voltage dips too low, it is possible to save files properly and then shut down the system by software, to avoid any data loss. 

Note: If the current value is negative, it means that the batteries are feeding the Raspberry Pi. If the current value is positive, it means that the batteries are being charged.

Safe and Stable Circuit Design

It provides protection to the circuits from overcharge/ over-discharge, over-current, short circuit, and reverse. Along with the equalizing charge feature, for a lot more safe and stable circuit.

5V USB Output

Convenient for powering other boards. The 8.4V interface is the charge port. You can plug the 8.4V 2A charger provided for charging the batteries.

Battery Warning Indicators

Easy to check if the battery is connected correctly. WARNING LEDs are the indicators of batteries, they turn on if you reverse batteries. Hence, you'll know if you've correctly connected or vice versa.

Note: Rechargeable 18650 Li Batteries are NOT INCLUDED.
