Understanding CM4 94V0 Schematics: Design, Compliance, and Practical Implementation

Introduction

When designing a custom carrier board for the Raspberry Pi Compute Module 4 (CM4) , two critical specifications often appear on the schematic and PCB layout: CM4 (the module itself) and 94V0 (the UL flammability rating of the PCB substrate). While seemingly unrelated, they converge in professional embedded design—ensuring both electrical functionality and regulatory safety.

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 cm4 94v0 schematics

1) Quick facts

• Module: Raspberry Pi Compute Module 4 (CM4).
• Typical deliverables you should have: official CM4 datasheet, CM4 IO board schematics (if available), and Raspberry Pi Foundation’s CM4 product brief and schematics.
• “94V-0” is a UL flammability rating for printed circuit board (PCB) materials (FR‑4 variants) — indicates the board material self‑extinguishes under test conditions.
• Use the official CM4 datasheet and mechanical drawings as primary reference for pinouts, power sequencing, and recommended decoupling.

: The CM4 uses PCIe Gen 2.0 and HDMI 2.0. These requires strict impedance control ( Module: Raspberry Pi Compute Module 4 (CM4)
