Waveshare PoE UPS Uninterruptible Power Supply Base Board for Raspberry Pi Compute Module 4 with Gigabit Ethernet/Dual HDMI/Quad USB2.0 Interfaces

Produktbeschreibung

• Standard CM4 Socket And Color-Coded Raspberry Pi 40PIN GPIO Header Suitable For Compute Module 4 Lite EMMC Series Module.
• It is able to charge the batteries and provide power output for the system 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.
• Protection Circuits For Over Charge Discharge, Over Current, Short Circuit, And Reverse-Proof Along With The Standalone Resettable Fuse For Each Battery, More Safe And Stable. Monitoring The Batteries Voltage, Current, Power, And Remaining Capacity Via I2C. When the voltage dips too low, it is possible to save files properly and then shutdown the system by software, to avoid any data loss.
• When the external power supply is insufficient, the battery will provide power output together with the external power supply at the same time to ensure system normal operation. When the external power supply is connected, the system will keep running normally even when the battery fails or is taken out. When the external power supply is disconnected, it will automatically switch over to batteries output without interrupting the system operation.
