While "94V-0" refers to the board's material properties, the are what you need for designing custom carrier boards or troubleshooting circuits. The Raspberry Pi Foundation provides comprehensive design files for the CM4 and its official IO board. Design Files - Raspberry Pi Compute Module 4 IO Board
Understanding the architecture of a circuit board is essential for hardware engineers, repair technicians, and embedded systems developers. The designation "94V-0" is not a specific model number, but rather a UL (Underwriters Laboratories) flame rating indicating that the printed circuit board (PCB) material is self-extinguishing within 10 seconds during a fire test. When combined with "CM4," this typically refers to the Raspberry Pi Compute Module 4 or compatible carrier boards engineered to meet strict industrial safety and flammability standards. cm4 94v0 schematics
Ensure your carrier board does not exceed the total 3.3V power budget provided by the CM4 module.
When analyzing or designing a custom carrier board schematic for a CM4 module, high-speed signals demand strict adherence to impedance matching and differential pair routing rules. PCI Express (PCIe Gen 2 x1) Disclaimer: The CM4 design files and schematics are
Since many manufacturers use the "CM4" label and the "94V0" mark, you must look for the or a specific Model Number printed on the PCB (usually in white silkscreen).
The module has on-board PMIC (Power Management IC) to generate 3.3V, 1.8V, and the low voltage needed for the RAM and SoC. 4. Gigabit Ethernet PHY The CM4 includes an onboard Broadcom BCM54210PE Gigabit Ethernet PHY When combined with "CM4," this typically refers to
