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 turn the CM5 template into a minimal bootable carrier: first I’ll inspect the module pins and CM5 power requirements, then add only the power input/regulation and required passives/pull resistors, wire them, and run validation.
Wirelessly connects nets on schematic. Used to organize schematics and separate functional blocks. To wirelessly connect net portals, give them same designator. #portal
