LORDWORLD PoE UPS Base Board for CM4 40PIN GPIO

SKU CH-H052-NFZ9G

PoE UPS base board powers a CM4 module with battery backup, real-time I2C monitoring, dual HDMI, four USB 2.0 ports and a 40-pin GPIO header

  • Standard CM4 socket plus colour-coded 40PIN GPIO header enables direct module integration
  • Dynamic path management across multiple power inputs delivers a more stable supply for continuous operation
  • Over-charge, over-discharge, over-current, short-circuit and reverse-polarity protection circuits safeguard the system
  • Per-battery resettable fuses add an extra layer of safety during charging and discharging
  • I2C monitoring reports battery voltage, current, power and remaining capacity in real time

PoE UPS Base Board for CM4

The LORDWORLD PoE UPS Base Board is a development carrier for Raspberry Pi Compute Module 4. It integrates a standard CM4 socket with a colour-coded 40-pin GPIO header. Dual HDMI and quad USB 2.0 ports provide video and peripheral connectivity. The board is supplied new and includes mounting holes on two sides.

Suitable for Compute Module 4 Lite and eMMC variants

Makers building battery-backed edge devices benefit from dynamic path management and I2C monitoring of voltage, current, power and remaining capacity. Protection circuits guard against over-charge, over-discharge, over-current, short circuit and reverse polarity. Builders who do not use a Compute Module 4 cannot populate the socket.

40-pin GPIO header matches Pi pinout

The colour-coded 40-pin header aligns with the Raspberry Pi 40-pin layout for direct HAT compatibility. Precise cut-outs with clear labels ensure every connector lines up with the board edges. A cooling fan and airflow vent assist thermal management during sustained operation.

Highlights

  • Standard CM4 socket plus colour-coded 40PIN GPIO header enables direct module integration
  • Dynamic path management across multiple power inputs delivers a more stable supply for continuous operation
  • Over-charge, over-discharge, over-current, short-circuit and reverse-polarity protection circuits safeguard the system
  • Per-battery resettable fuses add an extra layer of safety during charging and discharging
  • I2C monitoring reports battery voltage, current, power and remaining capacity in real time

Questions about this item

How long will the UPS keep a Compute Module 4 running on battery power?

Runtime depends on the battery capacity you install and the load the CM4 draws; the board monitors voltage, current, power and remaining capacity over I2C so you can track it in real time.

How hot or noisy does the board get during continuous operation?

A cooling fan and airflow vent are built in to dissipate heat from the CM4 and power circuitry, keeping temperatures down during all-day use.

What extra parts are required before this base board can operate?

You need a Raspberry Pi Compute Module 4 (Lite or eMMC) and at least one compatible Li-ion cell; the board provides the 40-pin GPIO header, dual HDMI, quad USB 2.0 and PoE input.
