The text "94V-0" on a Raspberry Pi Compute Module 4 (CM4) or its carrier board is not a model number. It is a safety rating. This guide helps you find the correct hardware schematics for your CM4 project. Understanding the 94V-0 Label
Are you designing a , or troubleshooting an existing one?
Raspberry Pi Ltd. has for the Compute Module 4 itself. Unlike the older CM1 or CM3, the internal design of the CM4 remains proprietary to prevent unauthorized cloning. CM4 schematic - Raspberry Pi Forums cm4 94v0 schematics
If you have noticed "94V-0" printed on a or its carrier boards, you aren't looking at a part number or a performance spec. Instead, this is a critical safety certification that ensures your industrial or commercial project won't literally go up in flames . What Does 94V-0 Mean on a CM4?
A standard CM4 carrier schematic must include the following blocks (all compatible with 94V0-rated laminate like FR-4): The text "94V-0" on a Raspberry Pi Compute
These are the interface points between the CM4 and the board. The schematic will show which pins handle the PCIe lanes, USB signals, and GPIO.
Because the CM4 lacks standard ports (like USB or HDMI) and relies on two 100-pin high-density Hirose connectors, Raspberry Pi provides the full, unrestricted schematics for the official . Understanding the 94V-0 Label Are you designing a
Elias had been a hobbyist until his brother, a lead engineer at Aetheris, vanished. The only thing left behind was a thumb drive labeled with a cryptic version number: CM4-Rev.X-94V0 .
Look for brand names like Waveshare, Seeed Studio, BigTreeTech, or Sourcekit printed on the silkscreen.
In the vast majority of modern electronics contexts, stands for the Raspberry Pi Compute Module 4 .
