Description:
My characteristics:
Raspberry Pi uninterruptible power supply (UPS) module.
Support simultaneous charging and discharging, and provide stable 5V power output.
Compatible with 4B/3B+/3B/3A+.
Based on Raspberry Pi 40pin GPIO interface, suitable for Raspberry Pi series motherboards
It can communicate through the 12C interface to measure parameters such as battery voltage, current, power and remaining power, and detect the working status of the module in real time.
Onboard battery protection circuit, anti-overcharge, anti-overdischarge, anti-overcurrent, anti-short circuit and anti-reverse connection, balanced charging, stable and safer work.
Onboard 5V voltage regulator chip, up to 2.5A continuous output current.
The onboard USB interface can output 5V power, which is convenient for powering other main control boards.
The onboard warning indicator is convenient to check whether the battery is connected reversely.
Provide complete supporting information manual.
My parameters:
Output voltage: 5V
Charging power supply: 8.4V 2A
Control interface: I2C
Product size: 56*85mm
Battery specification: 2600mAh 18650 lithium battery*2, in series (battery not included)
Through hole diameter: 3.0mm
Real-time detection of module working status
It can communicate through the I2C interface to measure parameters such as battery voltage, current, power and remaining power.
When the detection voltage is too low, you can use the program to control the Raspberry Pi to save the data and then shut it down to avoid data loss due to sudden power failure.
Safe and stable circuit design
The onboard battery protection circuit prevents overcharge, overdischarge, overcurrent, short circuit and reverse connection. Balanced charging, stable and safer work. 
Package include:
UPS HAT*1
8.4V battery charger*1
2*20PIN long row seat*1
RPI copper pillar package (2PCS sets) *1
