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

Thought for a moment

I’ll build the smallest practical CM5 support schematic: first I’ll inspect the CM5 pinout and requirements, then add only the essential power/regulation, decoupling, and required biasing, wire it, and run checks.

Found 3 results for Find an available USB Type-C receptacle connector part for a minimal Raspberry Pi CM5 carrier board power input. Needs VBUS, GND, CC1 and CC2 pins exposed; USB data not required. Prefer common surface-mount receptacle with through-hole shell tabs, current rating suitable for up to 5A USB-C PD if available..

Found 3 results for Find a 5V VBUS ESD TVS protection diode for USB-C power input on a Raspberry Pi CM5 carrier board. Needs working voltage around 5V, low capacitance not critical for VBUS, SMD package, suitable surge/ESD protection..

4/7 Add essential connectors, regulator/protection, decoupling, and required pull components

Thought for a moment

Minimum architecture selected: regulated 5 V enters through USB-C, CM5 handles its onboard 3.3 V/1.8 V regulation, and GPIO_VREF will be tied to CM5_3.3V for normal 3.3 V GPIO. I’m adding only the USB-C input, VBUS protection, and two input capacitors.

Wiring is complete. The remaining ERC items are expected unused CM5 interfaces and unused USB-C data/SBU pins, so I’m marking them explicitly as no-connect rather than adding expansion circuitry.

Thought for a moment

Done — I added a minimal CM5 bring-up schematic: USB-C 5 V input, VBUS TVS protection, 100 µF + 100 nF input capacitance, CC1/CC2 to the CM5, all 5 V/GND pins wired, GPIO_VREF tied to CM5_3.3V, and unused interfaces explicitly marked no-connect.
I also created Minimal CM5 Bring-Up Notes with the BOM, power budget, datasheet assumptions, and validation notes. Remaining review items are layout-stage airwires because the board is not placed/routed yet; U1:VBUS_EN is intentionally unused for this minimal boot-only design.
