The CM-4 94V-0 (often bearing the UL marking E162264) is not a specific motherboard model, but rather a manufacturing standard marking for a Printed Circuit Board (PCB) produced by HannStar Board Corp. The "94V-0" refers to the UL 94 flammability standard, indicating the board material is self-extinguishing within 10 seconds. Identifying Your SchematicComponents of CM-4 94V-0 Schematics
Why this matters for the schematic hunter:
When you see "94V-0" on a board, it tells you that the device was built to a commercial safety standard. It implies the device was mass-produced (likely for an industrial or consumer application) rather than being a home-brew prototype. It is a stamp of legitimacy. cm-4 94v-0 schematics
