Cm4 94v0 Schematics 2021

To find the actual design files and pinouts, you should refer to the following official resources:

The Raspberry Pi Compute Module 4 (CM4) is a compact system-on-module featuring the BCM2711 SoC, available in several RAM/flash and wireless configurations. Many hardware designers refer to the CM4’s PCB markings and the “94V-0” flammability rating when integrating the module into carrier boards. This post explains how to read and use CM4 schematics, key signals and power rails to connect on a carrier board, PCB material/flammability implications (94V-0), and practical design tips. cm4 94v0 schematics

If you are looking for schematics for the , it is important to clarify that "94V-0" is not a model number; it is a UL flammability rating for the PCB material, indicating the board will self-extinguish within 10 seconds during a fire test. To find the actual design files and pinouts,

The CM4 is essentially a "stripped-down" Raspberry Pi 4. It contains the core compute elements—the , RAM, and optional eMMC storage—but removes all physical ports. Instead, it uses two high-density 100-pin board-to-board connectors on the underside to expose its interfaces. Key interfaces provided by the CM4 schematics include: If you are looking for schematics for the
