ℹ
Products from the USA may come with an input voltage of 110V–120V, requiring a step-down transformer. Check the device wattage to select the correct power converter.
•Support: For Raspberry Pi CM4 POE UPS expansion board uninterruptible power supply (UPS), supports simultaneous charging and discharging, and supports dynamic route management.
•CM4 Connector: The onboard standard CM4 connector supports access to Compute Module4 Lite EMMC series motherboards.
•Power Supply: Dynamic route management of power supply in multiple ways, more stable power supply. Connecting to the external power supply will supply power to the system and charging the lithium battery at the same time; disconnecting the external power supply will automatically switch to the lithium battery power supply, which will not affect the normal operation of the system.
•Protection Circuit: On board circuit protection circuit, anti overcharge, anti over discharge, anti overcurrent, anti short circuit and anti reverse connection, and each battery is protected by an independent self recovery fuse, which is stable and safer.
•Multifunction: It can communicate through the I2C interface to measure parameters such as battery voltage, current, power and remaining power. When the voltage is detected to be too low, you can use the program to control the for Raspberry Pi, save the data and then shut down to avoid the sudden power failure of the CM4. data lost.
