1 Product Overview
The ED-CM4IND is an industrial embedded computer based on the Raspberry Pi CM4. Depending on the application scenarios and user requirements, it offers a variety of configurations for RAM, eMMC, or SD card storage.
- The available RAM options include 1GB, 2GB, 4GB and 8GB.
- The eMMC options include 0GB, 8GB, 16GB and 32GB.
- The SD card options include 0GB and 32GB.
TIP
When purchasing the product, either an SD card or eMMC must be selected, and they cannot be chosen simultaneously.
The ED-CM4IND provides commonly used interfaces such as HDMI, USB, RS232, RS485, DI, Relay, and ADC, and supports network connectivity via Wi-Fi, Ethernet, and 4G. Integrated with RTC and Buzzer, it enhances the product's ease of use and reliability, making it primarily suitable for industrial control and IoT applications.
