Green circuit board with CM4 socket, 40-pin LCD connector, RJ45 port and colour-coded GPIO header

LORDWORLD

LORDWORLD Mini Base Board (C) CM4 40PIN LCD Gigabit Ethernet RJ45

SKU CH-C78M-7TXDP

Mini base board for Raspberry Pi CM4 with 40-pin LCD connector and Gigabit Ethernet RJ45

  • Evaluate Raspberry Pi CM4 with standard socket and color-coded 40PIN GPIO header
  • Connect display and touch in one step using dedicated 40PIN LCD connector
  • Integrate faster into end products thanks to mini body with powerful functions
  • Support 70H-1024600-IPS-A series display with single connection for display and touch
  • Compatible with Compute Module 4 Lite and eMMC series modules for flexible deployment

Mini Base Board for CM4 Evaluation

The LORDWORLD Mini Base Board (C) provides a compact carrier for the Raspberry Pi Compute Module 4. It suits engineers who need to validate CM4 designs or embed the module directly into finished products. The board includes a standard CM4 socket and a colour-coded 40-pin GPIO header that matches the Raspberry Pi pinout.

Integration-Ready Layout Under Continuous Operation

A dedicated 40-pin LCD connector combines display and touch signals in a single link, reducing cable count during long test runs. The Gigabit Ethernet RJ45 interface maintains wired throughput without relying on wireless bandwidth. This layout keeps the board stable when the CM4 runs sustained workloads in enclosed or fanless enclosures.

40-Pin LCD Connector for 70H-1024600-IPS-A Series

The single 40-pin connector is designed for the 70H-1024600-IPS-A display family, so touch and video share one cable. Builders who need a different display interface or additional video outputs will need a separate adapter board. The board supports both Compute Module 4 Lite and eMMC variants.

Questions about this item

How much heat and noise should I expect from the Mini Base Board when it runs continuously with a CM4 installed?

The base board itself has no active cooling and draws negligible power, so heat and noise come almost entirely from the Compute Module 4 you fit and any attached display or HATs.

Which additional parts do I need to have on hand before this base board can boot and show video?

You must supply a Raspberry Pi Compute Module 4 (Lite or eMMC), a microSD card if using a Lite module, a 5 V power source, and a compatible display such as the 70H-1024600-IPS-A series that plugs into the 40PIN LCD connector.

Can I keep using my older Raspberry Pi HATs with the 40PIN GPIO header on this board?

The header follows the standard Raspberry Pi 40PIN layout, so HATs designed for that pinout will connect mechanically and electrically.
