Base board for Raspberry Pi CM4 modules. It integrates the function of an uninterruptible power supply, PoE circuit, it is equipped with connectors for all available interfaces, in addition, there is an RTC system on the board and a fan connector. Waveshare Compute Module 4 PoE Board
The PoE UPS Base Board is the base board for the Raspberry Pi CM4 modules. It is equipped with special connectors for connecting the module and the outputs of all CM4 interfaces, including USB, Ethernet, HDMI, DSI, CSI, 40-Pin GPIO connector compatible with HAT modules. Additionally, the board has a real-time clock (RTC) circuit and a fan connector. It integrates a PoE circuit that allows the set to be powered via an Ethernet cable.

An important element of the board is the function of an uninterruptible power supply (UPS). After connecting three 18650 batteries, it maintains a stable output voltage of 5 V even after the loss of power, which allows the device to continue operating and safely shut down. Full monitoring of the battery condition is possible thanks to the I2C interface. In addition, at the bottom of the board there is an M.2 M Key connector that allows you to connect an NVME SSD disk or communication modules. Full documentation is available on the product page.
