Cm-4 94v-0 Schematics

This block shows all the connections between the carrier board and the Hirose DF40 series connectors on the CM4. You'll see how the module's pins are routed to various peripherals.

The term is a UL 94 flammability standard for plastic materials. For a PCB, this means:

Look for silk-screened text (usually white or yellow ink) that looks like a model number. Common formats include: (Common in LED TVs) BN44-XXXXXX (Samsung Power Boards) EAX6XXXXXXX (LG Boards) 715GXXXX-XXXX (TPV/Philips Boards) 3. Search by the Device Model

When troubleshooting, repairing, or designing electronic systems, engineers frequently encounter the marking "94V-0" stamped onto printed circuit boards (PCBs). Often, this is accompanied by a manufacturer designation, such as "CM-4" or "FR-4."

Start with the official Raspberry Pi documentation, specifically for the Compute Module 4. While Raspberry Pi might not directly offer CM-4 94V-0, understanding the CM4 design can provide valuable insights.

Note down the part number printed on top of the main processor, power management IC (PMIC), or microcontroller. This block shows all the connections between the

A 94V-0 rating indicates that the material will self-extinguish within a very short timeframe—usually less than 0.1 seconds—after the ignition source is removed. No Drip: The material cannot produce flaming droplets.

It is a fire safety standard. Underwritten by UL (Underwriters Laboratories), the "94V-0" designation certifies that the PCB material (the fiberglass sheet itself) is . If the circuit board catches fire, the 94V-0 rating guarantees it will self-extinguish within 10 seconds once the flame source is removed. For a PCB, this means: Look for silk-screened

CM-4/FR-4 offers excellent electrical insulation, high mechanical strength, and superior adhesion.

The rigid FR-4/CM-4 material allows for rework, but high heat can cause the copper pads to delaminate from the substrate.
