② Unless otherwise specified, the Fan header usually is JST-SH type connector.
③ There's PoE header only on the Raspberry Pi official IO board without PoE circuit, which means additional PoE module is required for the official IO board to enable PoE feature.
Unless otherwise specified, the PoE feature here stands for integrating 802.3af-compliant PoE circuit (5V/2.5A).
Connecting with Compute Module 5

standard CM5 socket suitable for Compute Module 5 Lite / eMMC series module

* for reference only, please refer to the package content for detailed part list

4G / 5G module compatibility

compatible with communication modules with M.2 B KEY interface

* An additional communication module is required to enable 5G/4G/3G/2G cellular network function, recommended:SIM7600G-H-M.2,SIM8260G-M2, andSIM8262E-M2.

Supports connecting to M.2 NVMe Drive

Faster reading/writing speed compared to the TF card slot of Raspberry Pi, greatly improving reading/writing efficiency of the system or files, Supports booting Pi5 from NVME Solid State Drive

* for reference only, please refer to the package content for detailed part list

Applicable M.2 drive sizes
NVMe Drive Slot Support

* Only supports the NVMe Protocol Solid State Drives.

More rich interfaces

Features multiple interfaces including ETH / MIPI / HDMI / TF Card Slot / USB / M.2 B KEY / M KEY, easy to use

Precise cut-out with clear label

each cut-out is completely aligned with the connector

Heat Dissipation Design

Aluminum alloy case enables large-area heat conduction and dissipation, combined with heat sink fins, better heat dissipation

supports Rail mounting

Reserved Rail-mount buckle mounting holes for more convenient installation

* for reference only, the rail bracket is NOT included, please purchase separately.
