Description

The Raspberry Pi Compute Module 4 is designed for industrial applications and is the perfect option to embed Raspberry Pi functionality into your design. Based on the Raspberry Pi 4B, the CM4 Lite has a quad-core CPU with a BCM2711 processor running at 1.5GHz. The CM4L differs in form factor from previous compute modules, with additional new interfaces and a reduction in size. The CM4 L is available in and multiple RAM size options, both with and without Wi-Fi and is a cost effective option as it is supplied without the eMMC fitted.

Details

The Raspberry Pi Compute Module 4 Lite (CM4L) has been designed for use in embedded applications where Raspberry Pi functionalities are desired. The Raspberry Pi Compute Module 4 is based on the Raspberry Pi 4 Model B but comes in a more flexible form factor. It contains a Broadcom BCM2711 processor, the exact same processor you will find in the Raspberry Pi 4 Model B but it differs in many other areas including size and layout.

As the Compute Module is smaller in size than other Raspberry Pi Boards, it and can be integrated into industrial design easily. The new CM4 has some new interfaces that differ from previous Compute Modules including a second HDMI and PCIe.

The electrical interface of the CM4 is via two 100-pin high-density connectors. The total footprint of the CM4, including the socket, is smaller with the new form factor design.

If you’re looking for something with a small form factor, that is cost-effective and gives you the flexibility to customise to suit your designs, then the Compute Modules 4 Lite is an ideal choice.

How does the CM4 Lite differ from the CM4?

If we look at CM4 vs CM4L the main difference is that the CM4 Lite does not come with eMMC Flash and the SD/eMMC. However, you are able to connect your own SD/eMMC device to the compute module 4 Lite.
