Wiki,Tutorial,Program,Code,User Guide (Click here)


[] Do not include Raspberry Pi CM4 and other controller boards


[] Mini Uninterruptible Power Supply module Supports charging And Power output at the same time 5V 2.5A Output


[] Mini UPS expansion board for easy soldering or integration into mobile robots and industrial control equipments

[] I2C bus communication, monitoring the batteries voltage, current, power, and remaining capacity in real time

[] Onboard multiple function pins, provides two charging and discharging methods via pads and pin headers

[] Multiple battery protection circuits: over charge/discharge protection, over current protection, short circuit protection, and reverse protection, along with the equalizing charge feature, more safe and stable

[] Onboard 5V regulator, up to 2.5A continuous output current

[] Onboard warning indicators, easy to check if the battery is connected correctly and charging status

[] Comes with online development resources and manual



[] CHARGER : Support 5V 3A


[] BATTERY SUPPORT : 10440 Lithium battery × 3 (in parallel, NOT included)

[] DIMENSIONS : 61 × 38mm

Uninterruptible Power

[] 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

[] * for reference only, the CM4, CM4 base board, TF card and 10440 batteries are NOT included

Real Time Monitoring

[] Monitoring The Batteries Voltage, Current, Power, And Remaining Capacity Via I2C Interface

[] for reference only, please refer to the part list for detailed package content

Safe And Stable Circuit Design

[] Protection Circuits For Over Charge/Discharge, Over Current, Short Circuit, And Reverse

[] Along With The Equalizing Charge Feature, More Safe And Stable

What's On Board

7. UPS ON/OFF switch: Control UPS output

8. Boot button: Batteries activation

9. Power indicator: Lights up when the UPS switch is turned on

10. Charge indicator: 

Light up: when batteries are charging

Blinking: when batteries are abnormal or no battery connected

Light off: when charging completed or not charging

11. Reverse warning indicators: will light up if the related battery is reversely connected

12. Charging pad: 5V 3A

14. Multi-functional pin headers

Pinout Definition

[] IN : Power input (5V 3A)

[] OUT : UPS output (5V 2.5A)

[] GND : ground

[] UPS OFF : turn off UPS power output when connected to PWR pin

[] BOOT : Batteries activation (pull low for 500ms and then pull high)

[] CHARGE : Charge indication (low level indicates charging)

[] SCL : I2C clock

[] SDA : I2C data

[] PWR : UPS ON/OFF (turn off UPS power output when connected to UPS OFF pin)

[] Note: When using pin headers for charging and discharging, it is recommended to connect all input and output pins for 2.5A output current to reduce pin stress
