CM-4

The markings and 94V-0 are standard PCB identifiers that don't refer to a single specific device, but rather to the board's material and safety ratings. "94V-0" is a UL flammability rating indicating the board is fire-resistant, while "CM-4" is a manufacturing mark often associated with HannStar motherboards used in various laptop brands.

Raspberry Pi GitHub:

Raspberry Pi shares its hardware designs on GitHub. You may find KiCad and schematic files that could help understand the design considerations. UL 94 is a standard for flammability of plastic materials

• UL 94 is a standard for flammability of plastic materials.
• V-0 is the highest rating, meaning the material stops burning within 10 seconds on a vertical specimen, with no flaming drips.
