The Raspberry Pi Compute Module 3 (CM3) is a scaled-down version of the Raspberry Pi 3, designed for use in embedded systems and industrial applications where a compact, flexible form factor is required. The CM3 packs the same powerful Broadcom BCM2837 processor and 1GB of RAM found in the Raspberry Pi 3, making it capable of performing at speeds significantly faster than its predecessor, the Compute Module 1.
At the heart of the CM3 is the 1.2GHz 64-bit quad-core ARM Cortex-A53 CPU, which provides robust processing capabilities for a wide array of tasks. This is complemented by the 1GB of LPDDR2 SDRAM, ensuring smooth operation and the ability to handle memory-intensive applications. For non-volatile storage, the CM3 offers an optional 4GB eMMC Flash, allowing for a more reliable and faster storage solution compared to a traditional SD card.
The CM3 is built on a small 67.6mm x 31mm board, fitting into a standard DDR2 SODIMM connector, which makes it easy to integrate into custom designs. One of the significant advantages of the CM3 is its full flexibility in terms of GPIOs and interfaces when compared to the standard Raspberry Pi models. This allows for a broader range of connectivity options and the ability to interface with various external devices and sensors.
