Compact IO board for Compute Module 4

The LORDWORLD Mini Base Board (B) Full Version provides a credit-card-sized carrier for Raspberry Pi Compute Module 4. It mounts the standard CM4 socket and a colour-coded 40-pin GPIO header, supporting both Lite and eMMC module variants. The board is intended for evaluation or direct integration into finished devices.

Target users and limits

Engineers prototyping CM4-based appliances, robotics controllers or embedded gateways will find the onboard CSI, DSI, RTC, fan header, HDMI, USB, Gigabit RJ45, microSD slot and M.2 slot ready to use. Builders who require additional PCIe lanes, multiple camera interfaces or a larger form factor for extra headers should consider a different carrier.

Deciding specification

The single specification that determines fit is the standard CM4 socket paired with the 45 onboard connectors covering CSI, DSI, RTC, fan, HDMI, USB, Gigabit Ethernet, microSD and M.2 interfaces.

Questions about this item

Which Compute Module 4 variants does the standard CM4 socket on this board accept?

The standard CM4 socket fits both Compute Module 4 Lite and eMMC series modules, so either storage option works.

Will the colour-coded 40-pin GPIO header on this board mate with my existing Raspberry Pi HATs?

Yes, the onboard 40-pin GPIO header follows the Raspberry Pi 40-pin layout, so standard HATs and add-on boards connect directly.

After inserting a Compute Module 4, what indicates the board has booted correctly?

A successful boot shows the HDMI output active, the RJ45 Gigabit Ethernet link LEDs lit, and the micro SD card slot accessible for the operating system.
