Raspberry Pi Compute Module 4 2GB/32GB Wi-Fi

Raspberry Pi Compute Module 4 condenses the full processing capability of the Raspberry Pi 4 Model B into a compact system-on-module designed for embedded integration. This industrial‑ready computing module combines a 64‑bit quad‑core Broadcom BCM2711 processor, 2GB LPDDR4 memory, and 32GB onboard eMMC storage within a 55 × 40 mm footprint. The compact embedded computer supports dual 4K displays, advanced multimedia acceleration, PCIe connectivity, dual camera interfaces, and integrated wireless networking. Such hardware capabilities enable developers to integrate powerful Linux computing into robotics platforms, smart devices, industrial controllers, and custom electronics without redesigning a full single-board computer.

Note: 4 × M2.5 mounting holes are located at the four corners. All dimensions are measured in millimeters (mm).

Compact System-on-Module Architecture

This embedded computing module integrates the same Broadcom BCM2711 quad‑core Cortex‑A72 processor used in Raspberry Pi 4 Model B, delivering strong 64‑bit performance for edge computing, multimedia processing, and embedded Linux applications. The small form factor enables seamless integration into custom carrier boards or finished products where a traditional single-board computer would be too large. Onboard LPDDR4 memory and integrated eMMC storage reduce external component requirements while simplifying hardware design for industrial and commercial deployments.

Advanced Multimedia and Display Capability

The compact compute board supports dual display output with resolutions up to 4K, enabling high‑resolution visualization, digital signage, and interactive interfaces. Hardware video decoding supports H.265 at 4Kp60 and H.264 at 1080p60, while OpenGL ES 3.0 graphics acceleration provides smooth rendering for graphical applications. Multiple MIPI display and camera interfaces further expand multimedia flexibility, allowing developers to build machine‑vision systems, imaging platforms, or advanced user interface devices.

Industrial Connectivity and Flexible Integration

This embedded processor module includes a wide range of connectivity options designed for product integration. Interfaces include PCIe Gen 2 ×1, USB 2.0, dual camera connectors, and 28 GPIO signals for peripheral expansion. Dual‑band 2.4GHz and 5GHz wireless networking with Bluetooth 5.0 offers reliable connectivity for IoT devices, while modular certification for the wireless subsystem simplifies compliance testing. Both onboard antenna and external antenna configurations support flexible enclosure design and improved signal performance.
