LORDWORLD Nano Base Board (B) for CM4, 40PIN GPIO, USB 2.0, 3.5 mm audio

SKU CH-8KJM-HJZHM

Compact carrier board hosts a Compute Module 4 with 40-pin GPIO, Gigabit Ethernet, USB 2.0, DSI, CSI, HDMI, 3.5 mm audio and micro SD slot

  • Evaluates CM4 modules using standard socket
  • Matches CM4 footprint for tight enclosures
  • Exposes 40 GPIO pins for expansion
  • Adds Gigabit Ethernet plus USB 2.0 ports
  • Includes 3.5 mm audio jack and Micro SD slot

Compact carrier for Compute Module 4

The LORDWORLD Nano Base Board (B) fits the same footprint as the CM4 and provides a standard CM4 socket for evaluation or direct integration into space-constrained end products. It targets engineers and makers who need a minimal carrier without extra bulk.

Interfaces that shape the build

A 40-pin GPIO header, Gigabit Ethernet, USB 2.0 ports, DSI and CSI connectors, HDMI output and a 3.5 mm audio jack expose the CM4’s peripherals for sensors, displays, cameras and sound. A micro SD socket supports Compute Module 4 Lite variants that lack on-board eMMC storage.

Board-scale mounting implications

Because the PCB matches the CM4 outline, it slides into tight enclosures and aligns with existing mounting holes designed for the module itself. The CM4 is not included, so buyers must source the compute module separately before the carrier becomes functional.

Questions sur cet article

Will the micro SD card slot need replacement after heavy write cycles?

The micro SD card slot is a passive connector; only the inserted card wears with heavy writes and can be swapped without tools.

What limits sustained throughput on the Gigabit Ethernet port?

The USB 2.0 interface caps sustained network throughput well below the Gigabit Ethernet line rate.

How much heat does the board add when the CM4 runs all day?

The base board itself adds negligible heat; thermal load comes from the Compute Module 4 you install.
