The Raspberry Pi Compute Module 4 packs the power of a Raspberry Pi 4 into a compact system-on-module form factor. This variant includes wireless connectivity, 1GB RAM, and 8GB eMMC storage—ready for integration into custom hardware designs. Built on the 64-bit quad-core BCM2711 processor, the CM4 delivers significant performance improvements over previous generations with faster CPU cores, enhanced multimedia capabilities, and expanded interfaces. Key Features 1GB RAM – LPDDR4 memory 8GB eMMC Storage – Built-in flash storage, no SD card needed Wireless Connectivity – 2.4GHz/5GHz Wi-Fi and Bluetooth 5.0 BCM2711 Processor – 64-bit quad-core Cortex-A72 @ 1.5GHz VideoCore VI GPU – OpenGL ES 3.x support PCIe Interface – Single-lane PCIe 2.0 Specifications Video Decode: 4Kp60 H.265, 1080p60 H.264 Video Encode: 1080p30 H.264 Display: Dual HDMI (up to 4K), dual MIPI DSI Camera: Dual MIPI CSI-2 interfaces Ethernet: Gigabit PHY with IEEE 1588 GPIO: 28 pins (up to 6× UART, 6× I2C, 5× SPI) Dimensions: 55 × 40mm Ideal For Industrial and embedded applications Custom hardware designs IoT deployments Digital signage Thin clients Note: Requires a carrier board (such as the IO Board) for development and deployment. The CM4 uses high-density connectors, not standard GPIO headers.
