  • Simplify wiring using color-coded Raspberry Pi 40PIN GPIO header
  • Expand connectivity with onboard CSI camera, FAN, HDMI0, USB 2.0, RJ45 Gigabit Ethernet, Micro SD and M.2 slot
  • Compact board delivers powerful functions in mini body for faster application integration

LORDWORLD Mini Base Board Advanced Version

This compact development board provides a standard CM4 socket and colour-coded 40-pin GPIO header for Raspberry Pi Compute Module 4 evaluation. It accepts both Lite and eMMC module variants, giving engineers a small platform for rapid prototyping or integration into finished products.

Dedicated 40-pin LCD connector

A single 40-pin LCD connector handles display and touch signals, supporting Waveshare 70H-1024600-IPS-A series panels without extra wiring. The board also brings out CSI camera, fan header, HDMI0, USB 2.0, RJ45 Gigabit Ethernet, micro SD slot and an M.2 slot for expanded connectivity.

Standard CM4 socket defines module compatibility

The board only works with Raspberry Pi Compute Module 4 Lite or eMMC series modules; it cannot accept earlier Compute Module generations or non-CM4 boards. Buyers who need a carrier for CM3 or CM3+ modules must choose a different base board.

Questions about this item

How often will the micro SD card slot or M.2 slot need replacement under heavy write cycles?

The micro SD card slot and M.2 slot are passive connectors; only the inserted storage media wears out. Replace the SD card or M.2 drive when its own endurance rating is reached, not the board sockets.

Which onboard connector reaches its thermal or current limit first when the Compute Module 4 runs sustained workloads?

The FAN header and 40PIN GPIO header share the board's power budget. Under sustained load the CM4 itself throttles before any single onboard connector hits its rated limit, so active cooling via the FAN header is the practical ceiling.

How much fan noise and board heat appear when the CM4 and Gigabit Ethernet run continuously?

The board includes a FAN header for active cooling; noise and heat depend entirely on the fan you fit and the CM4's workload. The RJ45 Gigabit Ethernet port adds minimal extra heat.
