If you are inspecting a custom carrier board, a third-party baseboard, or an electronic device powered by a Raspberry Pi Compute Module 4 (CM4), you might encounter the text printed directly on the green or black fiberglass.

The CM4 exposes one PCIe Gen 2 lane.

Whether you are designing a brand-new carrier board in KiCad/Altium or repairing a broken board, keep these technical details in mind:

For the next hour, the world narrowed down to four points of contact. He carefully soldered thin magnet wire from the old pads to the new chip, suspended in mid-air above the board. It looked ugly—a "spider on a plate"—but the electrons wouldn't care about aesthetics. cm4 94v0 schematics

Look for the "nEXTRST" and "GLOBAL_EN" lines. These are vital for troubleshooting boards that refuse to boot or "eMMC" modules that won't flash. Troubleshooting Common CM4 Board Issues
