Add the minimum required set of components needed to run a simple project using the CM5. Keep the design as minimal and practical as possible while ensuring the module can boot and operate reliably.
Include only the essential supporting circuitry:
Power input and regulation
Decoupling capacitors
Required clocks or pull-ups/pull-downs
Avoid unnecessary features or complex expansion circuitry
Optimize for simplicity and fast prototyping
Keep the BOM as small as possible
I’ll build a minimal CM5 carrier schematic focused on reliable boot: confirm the CM5 required rails/control pins, select a simple 5 V input path with adequate decoupling, add only required pull resistors, wire it, then run ERC/review and fix real issues.
