In the rapidly evolving world of embedded systems and single-board computers (SBCs), the Raspberry Pi Compute Module 4 (CM4) has emerged as a cornerstone for industrial designers, hobbyists, and engineers. However, as with any complex hardware, troubleshooting, reverse engineering, and repair require more than just a multimeter—they require a map. That map is known as a .
