CM5 PoE IO Board

Worked for 3 mins 50 sec

I created a new editable project for the full board here:
/mattmarquis17/cm5-um982-rtk-io-board

What was accomplished:

Identified the Amazon link as an MJRTK-UM982 / Unicore UM982 dual-antenna RTK GNSS module, not a CM5 IO board.
Captured your target: Raspberry Pi CM5 IO board + PoE af/at minimum + USB-C power input + four USB-C USB 3-capable ports + UM982 GNSS with two SMA antenna ports.
Started a dedicated build thread in the new project, and it reached completion:
/mattmarquis17/cm5-um982-rtk-io-board
The build thread created project files including a Project Specification and Architecture / Power Budget notes.

Open items:

Your account currently has no available ACUs, so I can’t continue inspecting or modifying the project from here.
The schematic and generated files should be reviewed in the new project once ACUs are available again.
Key design risk to review: 5 V 2 A is likely not enough for full CM5 + four USB ports; CM5-class designs often need closer to 5 V 5 A for full performance.

Suggested next steps:

Open the new project and review the files/specification.
Check whether the schematic was fully built or stopped on missing library parts.
When ACUs are available, ask me to “review the CM5 UM982 RTK IO Board project and continue from where it stopped.”

Review and continue

Check schematic issues

Increase power budget
