Cm-4 94v-0 Schematics |verified| May 2026

The markings "CM-4 94V-0" do not refer to a specific device model, but rather to the manufacturing standards and material certifications of the circuit board itself.

Flammability Rating: UL 94V-0 (Highest level of fire resistance for PCBs). cm-4 94v-0 schematics

• CM‑4 IO Board schematic – the baseboard you plug the CM‑4 into.
  Official name: Compute Module 4 IO Board – this is what most engineers need.

Usually near the "CM-4" marking, you will see a code starting with "E" followed by several digits (e.g., E123456). The markings "CM-4 94V-0" do not refer to
