Overview

The Raspberry Pi Compute Module 4 CM4004000ET is a high-performance system-on-module featuring a quad-core Cortex-A72 processor and 4GB of LPDDR4 RAM. This specific 'Lite' variant lacks on-board eMMC storage and wireless connectivity, and is designed for an extended temperature range of -40 to +85 degrees Celsius. It breaks out essential interfaces like PCIe Gen 2, HDMI, and MIPI to high-density connectors for integration into custom industrial carrier boards.

Why Choose This Part

This module provides the power of the Raspberry Pi 4 in a compact 55mm x 40mm form factor optimized for industrial integration. The 4GB RAM capacity and extended temperature range provide significant headroom for complex Linux-based applications in extreme climates.

Applications

Industrial Edge Gateways
The extended temperature rating makes it suitable for harsh environments where data processing is required at the edge.
Digital Signage
Utilizes hardware video decode and dual HDMI support to drive high-resolution displays in commercial settings.
Robotic Controllers
Low-latency PCIe Gen 2 and GPIO access allow for interfacing with motor controllers and custom vision processing hardware.

Getting Started

To use this 'Lite' module, engineers must provide an external SD card or eMMC interface on a carrier board such as the Compute Module 4 IO Board. Software development typically involves flashing a Raspberry Pi OS image to an SD card and using the standard Raspberry Pi toolchain for ARM v8.

Also Consider
