Contains pinout diagrams, mechanical dimensions, and electrical specifications.
Designing a custom board (often labeled 94V-0) requires adhering to the specific pinout of the two high-density Hirose DF40 connectors on the underside of the CM4. A. Power Supply Requirements The CM4 module requires a strict
The heart of any CM4 carrier board schematic is the pair of Hirose DF40 dual-beam connectors. The schematic will show how these 200 pins interface with the rest of the board, mapping the Broadcom BCM2711 processor lines to physical hardware traces. 3. Peripheral Interface Traces cm4 94v0 schematics
If you are looking for schematics to build a carrier board or understand the module's layout, here is a guide to the essential resources and technical details. 1. Official Raspberry Pi CM4 Schematics
It certifies that the board materials will self-extinguish within 10 seconds during a fire test. Power Supply Requirements The CM4 module requires a
This is the most error-prone area of .
If you are using the CM4 schematics to design a custom PCB, pay strict attention to the high-speed differential pairs indicated in the circuit diagrams. PCIe Gen 2 x1 Lane The PCIe interface requires precise impedance matching. Peripheral Interface Traces If you are looking for

Power rail requirements (+12V, +5V, +3.3V, and global ground).
Understanding the terminology around is essential for engineers and hobbyists looking to integrate Raspberry Pi hardware into custom, industrial-grade products.
designation is not a technical feature of the CM4's electronic circuit itself, but a UL 94 flammability standard for the PCB material. Raspberry Pi Compute Module 4
