Raspberry Pi Compute Module 4
Raspberry Pi Compute Module 4 (CM4) is a compute module based on the BCM2711 SoC with a 4-core Cortex-A72 @ 1.5 GHz. With 32 SKU variants (4 RAM × 4 eMMC × WiFi/no-WiFi options) it is highly versatile. It connects to a carrier board via a 100-pin connector (DDR4 SO-DIMM shape-compatible but electrically incompatible). The PCIe Gen2 ×1 interface enables NVMe SSDs, network cards, or camera modules. Available in extended-temperature variant (−40°C to +85°C).

Which group Raspberry Pi Compute Module 4 belongs to and how it is built
Compute Modules is a subcategory of hardware components that provide processing power for robotic systems. It encompasses onboard computers, single-board computers (SBCs), AI accelerators, embedded processors, GPU/NPU compute modules, and other units responsible for processing sensor data and executing control logic. These modules form the foundation of modern autonomous, humanoid, and perception-capable robots.
A Single Board Computer (SBC) is a complete computer integrated onto a single board, incorporating a processor, memory, communication interfaces, and I/O. In robotics, SBCs serve as local controllers, software hosts, integration modules, perception processing units, or communication management nodes. They are widely used in embedded systems, prototypes, mobile robots, and educational platforms.
