The rating is achieved via a vertical burn test, which is more stringent than horizontal tests because it simulates how real fires spread upward.
To view the internal layout, traces, and component locations of the CM4 or its IO board, you should use the official or Altium design files provided by Raspberry Pi. Recommended Design Files cm4 94v0 boardview new
: Signals like USB 2.0 and HDMI require specific trace widths and gaps to maintain proper impedance (e.g., 90 ohms for USB). The rating is achieved via a vertical burn
The "94V-0" label on your board refers to the , indicating that the PCB material is self-extinguishing and meets specific safety requirements for electronics. Form Factor: The CM4 measures The "94V-0" label on your board refers to
