Compatibility and revision notes

2.4/5 GHz 802.11ac Wi-Fi and Bluetooth 4.2/BLE are onboard. The wired Ethernet connector is Gigabit-rated but practical throughput is limited by its USB 2.0 connection. Raspberry Pi 3 Model B cases/accessories may differ from the B+ thermal and port layout.

Physical socket fit alone does not establish compatibility. Verify the exact processor support list, minimum BIOS, memory population rules, case dimensions, power connectors and shared-lane behavior in the cited model documentation before installation.

Preservation and repair

Avoid flexing the PCB or probing the fine-pitch CSI/DSI connectors while powered. Inspect the microSD socket, micro-USB power connector and soldered Ethernet/USB jack for mechanical stress; check supply voltage under load before diagnosing random resets.

For an archive record, photograph the PCB and labels before cleaning; note serial/date codes, BIOS/BMC versions, accessories, known faults, repairs, and test conditions. Use ESD-safe handling and never apply power with loose conductive hardware beneath the board.
