CM4 94V‑0 Schematics — Full Write-up
Overview
CM4 94V‑0 appears to combine two separate topics often searched together:
The CM4 is essentially a "stripped-down" Raspberry Pi 4. It contains the core compute elements—the Broadcom BCM2711 quad-core processor, 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: cm4 94v0 schematics

6) Useful reference documents (obtain from Raspberry Pi)
- CM4 datasheet and mechanical drawing
- CM4 IO board schematics and reference carrier designs
- Raspberry Pi hardware design notes and application notes for high-speed routing
Recommended EDA Software
- KiCad 7/8 – Free, with CM4 connector footprints and symbol libraries.
- Altium Designer – Professional, with activeBOM for 94V0 material tracking.
- EasyEDA – For quick JLCPCB fabrication (JLC’s standard FR-4 is 94V0).
He minimized the PDF. It was just a file, a digital ghost of a product long forgotten. But for a few hours, those lines and numbers had given him the power to raise the dead. He saved the schematic into his "Mastered" folder and turned off the lamp. CM4 datasheet and mechanical drawing CM4 IO board
The "94v0" marking often seen on industrial-grade boards like CM4 carrier boards indicates compliance with the Underwriters Laboratories (UL) 94 standard. A 94V-0 rating means:
- Go to the Waveshare Wiki.
- Search for your specific model (e.g., "CM4-IO-BASE-A").
- Navigate to the "Resources" or "Download" section.
- Look for a file named
Schematics.pdforCM4-IO-BASE-Schematic.pdf.
Step 3: Verify High-Signal Routing Hints
Though not in schematics, 94V0 layouts require impedance matching. Schematics will specify:
