Raspberry Pi CM4 Computing Module Core Board with Quad-Core A72 and eMMC for Embedded Designs
The Raspberry Pi Compute Module 4 (CM4) brings the power of Raspberry Pi 4 into a compact, embedded-ready board. Designed for industrial applications and deeply embedded systems, it integrates a quad-core ARM Cortex-A72 processor, dual video output, and a wide choice of RAM, eMMC flash, and wireless module configurations. With a board-to-board connector design for reliable connectivity, Gigabit Ethernet with IEEE 1588, and a PCIe expansion port, this module is well suited for network application development, large-scale data compilation, and custom industrial projects.
Processor, Memory and Performance
The CM4 uses an upgraded BCM2711 processor with a quad-core Cortex-A72 64-bit architecture for significantly faster computation than previous generations. Memory and storage options allow flexibility depending on project requirements.
BCM2711 64-bit Processor
Featuring a quad-core ARM Cortex-A72 CPU running at up to 1.5GHz, the CM4 delivers robust multi-threaded performance suitable for tasks like data processing, real-time control, and multimedia handling. The 64-bit architecture improves memory addressing and efficiency.
RAM Options 1GB to 8GB
Available in 1GB, 2GB, 4GB, and 8GB LPDDR4 RAM configurations, the CM4 supports large data compilation and memory-intensive applications. More memory capacity helps in handling larger datasets and smoother multitasking in embedded environments.
eMMC Flash Up to 100 MB/s
The eMMC flash memory on board offers transfer rates up to 100 MB/s, about four times faster than the CM3+. This delivers quicker boot times, faster application loading, and improved responsiveness for data-logging and storage-heavy tasks.
Connectivity and Expansion
Modern interfaces such as Gigabit Ethernet, PCIe, and wireless options give the CM4 flexibility for networking, expansion, and industrial connectivity. The board-to-board connector design replaces earlier gold finger connectors for increased reliability.
WiFi and Bluetooth Options
Wireless module options include the same WiFi and Bluetooth modules as the Raspberry Pi 4B, with both an onboard PCB antenna and provision for an external antenna. The external antenna is especially beneficial in metal enclosures or industrial settings where signal strength is critical.
Gigabit Ethernet with IEEE 1588
Onboard Gigabit Ethernet includes support for IEEE 1588 precision time protocol, making the CM4 suitable for networked industrial control, time-synchronized data acquisition, and automation systems that require accurate timing.
PCIe Port for Module Expansion
A dedicated PCIe port enables the addition of compatible modules such as NVMe storage, AI accelerators, or custom expansion cards. This flexibility allows developers to tailor the CM4 for specialized applications beyond standard Raspberry Pi offerings.
Uses and Applications
The compact form factor and industrial-focused features make the CM4 ideal for embedded projects, networking equipment, digital signage, and automation systems where reliability and performance are required.
Embedded Systems and Industrial Use
The B to B connector ensures stable connections in high-vibration environments, and the availability of wireless options with external antenna support suits industrial IoT gateways, remote monitoring units, and control systems.
Network Application Development
Gigabit Ethernet with IEEE 1588 and PCIe expansion make the CM4 well suited for custom network switches, time-sensitive networking devices, and edge computing nodes that require high-speed data transfer and precise synchronization.
Benefits and Buying Value
Choosing the CM4 means leveraging Raspberry Pi 4 performance in a modular, embedded-friendly package. The range of memory and storage options allows you to match the module exactly to your project's needs without overpaying for unused capabilities.
Scalability with Memory and Storage Choices
With RAM from 1GB to 8GB and eMMC capacities from 0GB (lite) to 32GB (plus further options via model numbers), you can select the exact configuration for your workload, from lightweight control to data-heavy applications.
Reliable Industrial-Grade Connection
The board-to-board connector design improves durability and simplifies integration into custom carrier boards. Combined with the onboard Gigabit Ethernet and PCIe, this module provides a stable, expandable computing core for demanding environments.
