Cm4 94v0 Schematics May 2026

A schematic set without a fabrication drawing that states: “Material: FR-4, UL94 V-0” is incomplete. Always demand both.

The Raspberry Pi Compute Module 4 (CM4) has revolutionized the world of embedded industrial design. Unlike its consumer-grade siblings (the Pi 4 Model B), the CM4 is a "bare-bones" System on Module (SoM) designed to be plugged into a custom carrier board. When engineers begin searching for "cm4 94v0 schematics," they are at the critical intersection of hardware design, safety certification, and performance optimization.

But what does "94V0" mean in this context, and why are the schematics so vital? This article breaks down the anatomy of CM4 carrier board schematics, the significance of the 94V0 flammability rating, and how to use reference designs to build industrial-grade products. cm4 94v0 schematics

Raspberry Pi publishes full schematics for the CM4 IO Board:

| Interface | Typical Use in 94V0 Designs | |-----------|-----------------------------| | Gigabit Ethernet | RTL8211F or LAN7518 (USB hub + Ethernet) | | USB 3.0 | VL805 (if CM4 lacks onboard USB 3.0) | | PCIe | M.2 Key M slot for NVMe SSD | | HDMI | ESD protection arrays (e.g., TPD4E02B04) | | MicroSD | Level shifters for 1.8V/3.3V (TXS02612) | A schematic set without a fabrication drawing that

The CM4 exposes one PCIe Gen 2 lane.
