These files can be found directly on the official Raspberry Pi Documentation portal under the Compute Module section. 3. Structural Breakdown of a CM4 Carrier Board Circuit

A is not a special variant of Compute Module 4 design but rather a professional implementation that combines the CM4’s electrical interface requirements with the safety and material standards of a 94V0-rated PCB. When creating such a carrier board, the schematic must correctly route power, high-speed interfaces, and boot options, while the accompanying PCB layout and fabrication notes must specify UL 94V-0 FR-4 material. cm4 94v0 schematics

The "94V-0" marking found on many CM4 and carrier board PCBs refers to the . This rating indicates that the circuit board material is self-extinguishing within 10 seconds of being exposed to a vertical flame and does not produce flaming drips.

CM4 has only one USB 2.0 interface (unless you use PCIe to USB). Many schematics short both USB ports to the same D+/D- – this fails. When creating such a carrier board, the schematic

Raspberry Pi does not release the full internal schematics for the CM4 module itself (as it is a proprietary design), but they provide extensive documentation for the
