The keyword "cm4 94v0" typically refers to one of two things: the Raspberry Pi Compute Module 4 (CM4) System-on-Module or the Orange Pi CM4, both of which are commonly mounted on carrier boards featuring the UL 94V-0 flammability rating.
| Feature | What to look for in the schematic | | :--- | :--- | | Board Thickness | Notes: "1.6mm FR-4 UL94V-0" or "0.8mm for 4-layer stackup" | | Clearance & Creepage | AC mains? No. For 5V/12V: >0.2mm spacing. For 240V (rare on CM4), much higher. | | Material Callout | A specific line in the schematic title block: "PCB: FR-4, TG130-140, UL94V-0" | | Thermal Relief | Copper pours on power supplies (e.g., 5V rail for CM4 draws up to 2.5A). | | Solder Mask | Not strictly 94V0 but required for UL: Must be rated (e.g., Taiyo PSR-4000). | cm4 94v0 schematics free
