Their reTerminal and Dual Gigabit Carrier Boards have public GitHub repositories containing hardware design files and schematic sheets. 4. Key Sub-Circuits to Look For in the Schematic
Search for "Raspberry Pi Compute Module 4 IO Board schematics" (official PDF). Use these as your literal template. Do not redesign the power sequencing logic—copy it. cm-4 94v-0 schematics
Since a single "universal" schematic for every board labeled CM-4 does not exist, technical reviews and repairs generally focus on the following standard subsystems: Power Delivery System: Their reTerminal and Dual Gigabit Carrier Boards have
If you are utilizing these schematics as a reference layout to build your own custom CM-4 compliant carrier PCB, pay strict attention to these hardware design rules: Use these as your literal template
If you are working on a specific piece of hardware, locating the (often silk-screened on the board) will lead you to the correct schematics , even if it just says "94V-0" on the surface.
