Green circuit board with CM4 socket and color-coded 40-pin GPIO header

LORDWORLD

LORDWORLD CM4 IO Board Type B PoE 40PIN GPIO 232 485

SKU CH-CN1C-C0YQ8

IO board for Raspberry Pi Compute Module 4 with PoE, color-coded 40-pin GPIO and RS232/RS485 connectors

  • Ready for CM4 evaluation with standard socket and colour-coded 40PIN GPIO header
  • Integrates into end products using all Compute Module 4 variants
  • Powers Pi projects via PoE for simplified industrial deployment
  • Expands connectivity with CSI, DSI, HDMI, USB, Ethernet, PCIe, RS232 and RS485
  • Industrial-grade interfaces include 232 and 485 serial ports for robust communication

CM4 IO Board with PoE and Industrial I/O

This LORDWORLD board hosts any Compute Module 4 variant and adds Power over Ethernet so the module can draw power from the network cable. A standard CM4 socket and a colour-coded 40-pin GPIO header keep pin identification simple during development. On-board connectors cover CSI, DSI, HDMI, USB, Ethernet, PCIe, RS232 and RS485 in a single package. It suits engineers evaluating the CM4 or embedding it into finished products.

Industrial integrators and PoE deployments

The board targets builders who need RS232 or RS485 serial links alongside camera, display and high-speed expansion in industrial or PoE-powered projects. Makers without a Compute Module 4 gain nothing, and users who only require basic GPIO breakout will find the peripheral set excessive. Projects that must run from a DC jack or USB-C power source instead of Ethernet should choose a different carrier.

PoE-powered carrier with RS232 and RS485

The deciding specification is the combination of PoE input plus onboard RS232 and RS485 transceivers, which lets the CM4 communicate with legacy industrial gear while receiving both data and power over one Ethernet connection. If your design needs neither PoE nor those serial interfaces, a simpler carrier will cost less and fit tighter spaces.

Questions about this item

What physical space does the LORDWORLD CM4 IO Board Type B need for the Compute Module 4 socket and 40PIN GPIO header?

The board uses a standard CM4 socket and a colour-coded 40PIN GPIO header that matches the Raspberry Pi pin layout, so it fits any enclosure designed for the official Compute Module 4 form factor.

How is the board installed, and which step is often missed?

Insert the Compute Module 4 into the CM4 socket until it clicks, then secure it with the mounting holes; the step many miss is enabling the PoE feature in the CM4 EEPROM configuration before first boot.

What maintenance or replacement will the RS232 and RS485 interfaces need over time?

The onboard RS232 and RS485 transceivers are industrial-grade parts rated for long-term use; only the terminal-block connectors may need re-tightening if vibration loosens the wiring.
