M5Stack has designed CM4Stack, a development kit based on the Raspberry Pi Compute Module 4 for industrial automation and smart home applications. M5Stack has always been developing IoT boards and modules for increased adoption among maker communication and professional embedded hardware and software engineers.
The CM4Stack host board includes a capacitive touch display with a resolution of 320×240 pixels. This 2-inch IPS LCD screen is a high-quality display that can display high-quality images and videos. The capacitive touch screen allows for intuitive and responsive touch functions, which makes it ideal for projects that require user interaction.
The M5Stack can be installed using DIN rail, wall hanging, and screw fixing methods. The DIN rail method is commonly used in industrial automation applications, where devices are mounted on DIN rails for easy installation and maintenance. M5Stack’s DIN rail mounting option allows it to be easily integrated into industrial control systems and other similar applications.
