LORDWORLD CM4 to Pi 4B Adapter USB 3.0 eMMC development board

SKU CH-15FF-H02J7

Adapts a Compute Module 4 into a Pi 4B form factor with four USB 3.0 ports and eMMC storage support for wider temperature operation

  • Four USB 3.0 channels replace the slower 2.0 interface
  • On-board eMMC support avoids TF-card instability
  • Wider operating temperature range suits demanding environments
  • Converts a Compute Module 4 into a Pi 4B form factor
  • Alternative solution when a standard Pi 4B is unavailable

CM4 to Pi 4B Adapter

This adapter lets a Compute Module 4 replicate the physical form factor of a Raspberry Pi 4 Model B. It targets developers and makers who want the CM4's flexibility in a standard Pi 4B footprint for embedded or edge projects.

Four USB 3.0 ports and eMMC support

The board provides four USB 3.0 channels, replacing the slower USB 2.0 interfaces found on the standard Pi 4B. An onboard eMMC socket offers more reliable storage than a microSD card for industrial or vibration-prone deployments.

USB 3.0 bandwidth and thermal limits

The four ports share the CM4's single PCIe Gen 2 x1 lane, so aggregate throughput is capped by that link. The adapter has no active cooling, so sustained high-speed transfers or wide-temperature operation may require external airflow or heatsinking.

Questions sur cet article

What USB standard do the four ports on this adapter use, and what does that mean for transfer speed?

The adapter provides four USB 3.0 ports, replacing the original USB 2.0 interface for significantly faster data transfers.

What physical space and mounting does this board require to fit a Raspberry Pi CM4 module?

It reproduces the Pi 4B form factor, so it fits standard Pi 4B cases and uses the CM4's two mounting holes for secure attachment.

How do you install a Compute Module 4 onto this adapter, and which step do builders often miss?

Align the CM4's connector with the adapter's socket, press down firmly until the module clicks into the retention clips, then secure the two mounting screws.
