NOTE① USB 3.0 is equivalent to USB 3.2 Gen1
② There's PoE header only on the Raspberry Pi official IO board without PoE circuit, that 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 4

Standard CM4 Socket And Color-Coded Raspberry Pi 40PIN GPIO Header
Suitable For Compute Module 4 Lite/EMMC Series Module

Rich Interfaces

Precise Cut-Out With Clear Label

Each Cut-Out Is Completely Aligned With The Connector

Cooling Fan Included

Comes With Cooling Fan, Combined With The Airflow Vent, Better Heat Dissipation

Wall Mount Support

Wall Mount Holes On Two Sides, Handy For Mounting


Application Examples

Binocular Vision Raspberry Pi Projects, Or Other Industrial Context

for reference only, display, cameras, and antenna are NOT included.
