CM4 Maker Board
Description
Seeking for the ideal carrier board for your Raspberry Pi Compute Module 4 (CM4)? Introducing the CM4 Maker Board.
Optional: Raspberry Pi CM4 board & coin cell battery.
What is the Raspberry Pi Compute Module 4?
Compute Module 4 is officially launched on 19th October 2020, and there are 32 variants of the module to choose from.
The Raspberry Pi Compute Module 4 (CM4) and Compute Module 4 Lite (CM4Lite) are loosely based on the Raspberry Pi 4 Model B. The CM4 has an option for cost-sensitive applications to be supplied without the eMMC fitted; this version is called the CM4Lite. The form factor of the new CM4 and CM4L is different from previous Compute modules, which have all shared a form factor. The change is due to the addition of new interfaces; a second HDMI, PCIe, and Ethernet. The addition of these new interfaces, especially PCIe, would not have been possible while preserving the older form factor. Instead, the electrical interface of the CM4 is via two 100-pin high-density connectors. While the switch to a newer form factor has allowed a reduction in the footprint. The total footprint of the CM4, including the socket, is smaller with the new form factor design.
