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.
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).
