A notable trend in the "new" CM4 ecosystem is the shift toward . Since JLCPCB offers 94V0-rated fabrication at low costs, many open-source CM4 carrier boards are now distributed as full editable projects.
While Raspberry Pi has not released official schematics for the CM4 module itself, they provide comprehensive design files for the , which serves as the primary reference for boardview and layout. cm4 94v0 boardview new
These files allow you to see exact trace routing and component placement for high-speed interfaces like PCIe, USB 2.0, and dual HDMI. A notable trend in the "new" CM4 ecosystem
The Raspberry Pi Compute Module 4 is used in various applications, including IoT devices, thin clients, industrial automation, and more. Its small form factor and flexibility make it an attractive option for product developers. These files allow you to see exact trace
The CM4 moved away from the SODIMM form factor of previous generations to a "high-density" design featuring on the underside. This change was specifically intended to improve signal integrity and allow for more compact carrier board designs.
