. It indicates that the PCB material is fire-resistant and will stop burning within 10 seconds on a vertical specimen. It is a common safety certification for electronics and is not a model number for the board itself. : A file (often in cm4+94v0+boardview
This is the . A 94V0 rating means the circuit board is flame retardant. It will self-extinguish within 10 seconds of an open flame being removed. Why does this matter? If you have a non-branded CM4 board (often
The CM4 breaks out PCIe Gen 2, Dual HDMI, and MIPI CSI/DSI. Because these traces are differential pairs, a boardview is essential to ensure that a repair (like a jumper wire) maintains the correct length and impedance. 3. The 100-Pin High-Density Connectors : A file (often in This is the
