- Reverse engineered schematic and layout for Raspberry Pi Compute Module 5 (CM5) for educational/hacking purposes.
- Not suitable for fabrication due to signal integrity issues, incomplete BOM, and custom/unavailable chips.
- Includes bonus schematic for RM0 WiFi/Bluetooth module, useful for solving design issues.
- Board analysis involved sanding layers, scanning at 9600 DPI, and using KiCad for tracing.
- 10-layer PCB with 2+6+2 microvia configuration and specific layer functions detailed.
- PMIC features hot-swap for inrush current control; WiFi/Bluetooth can be disabled via GPIO.
- CM5 with eMMC doesn’t conflict with external SD cards as SD pins are unconnected.
- Test points and their coordinates provided for debugging and power monitoring.
- Unidentified pins listed, with some guesses (e.g., USB 2.0).
- PMIC I2C register map and net identification for PCIe/RP1-BCM2712 remain unexplored.
