CM4Stack Raspberry Pi CM4 All-in-One Micro Host

CM4Stack is an all-in-one industrial micro host built on the Raspberry Pi Compute Module 4 (CM4), using the CM4104032 variant with built-in Wi-Fi, 4 GB RAM, and 32 GB eMMC storage. 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.

Note

When connecting to CM4Stack, it is recommended to use a high-quality USB cable certified by USB-IF to prevent device malfunction.
