It delivers stable computing performance in a compact, industrial-grade design. Designed for edge and control scenarios, CM4Stack is suitable for industrial automation, smart home systems, IoT gateways, and embedded control applications. Integrated Touch Display & Multimedia CM4Stack features a 2.0-inch IPS LCD with capacitive touch and a resolution of 320 × 240, enabling intuitive local interaction. A dedicated high-resolution multimedia interface supports external display expansion. High-Speed Connectivity & I/O 2 × USB 3.2 Type-A ports (PCIe + ASM3042) for high-speed peripherals 1 × USB Type-C (USB 2.0) supporting OTG and host power supply 1 × Gigabit Ethernet (RJ45) for reliable wired networking 1 × DC-JACK power input (12 V @ 3 A) Expansion & Industrial Interfaces For flexible system expansion, CM4Stack includes 2 × HY2.0-4P expansion ports providing I2C and UART interfaces, enabling easy connection to sensors, controllers, and external modules. Audio, Security & System Management Audio output is handled by a built-in 2 W speaker driven by an AW88298 16-bit I2S amplifier. For enhanced system security, CM4Stack integrates an ATECC608B hardware security encryption chip. Timekeeping and power management are supported by an onboard BM8563 RTC, ensuring accurate timing for scheduled tasks and low-power operation. Thermal Design & Mechanical Installation CM4Stack features an active cooling fan combined with an aluminum alloy heat dissipation frame to maintain stable performance under continuous load. The enclosure supports DIN-rail mounting, wall mounting, and screw fixing, allowing flexible installation in control cabinets, enclosures, or embedded systems. Application Scenarios CM4Stack is ideal for industrial automation, smart home control, IoT edge computing, and other embedded Linux applications that require a compact, reliable, and expandable Raspberry Pi CM4-based platform.
