Description CM4Stack is an all-in-one industrial micro host based on the Raspberry Pi Compute Module 4, using the CM4104032 module with built-in Wi-Fi, 4GB RAM, and 32GB eMMC storage. It integrates a 2.0-inch IPS LCD with capacitive touch, 320 x 240 resolution, dual USB 3.2 Type-A ports, USB Type-C, Gigabit Ethernet, DC power input, high-resolution multimedia signal interface, and two HY2.0-4P expansion ports for I2C and UART. CM4Stack also includes a 2W speaker with AW88298 16-bit I2S amplifier, ATECC608B security encryption chip, BM8563 RTC, active cooling fan, and aluminum alloy heat dissipation frame. It supports DIN-rail mounting, wall mounting, and screw fixing for industrial automation, smart home, IoT, and embedded control applications. Note: When connecting to CM4Stack, it is recommended to use a high-quality USB cable certified by USB-IF to prevent device malfunction.
