CM4 Industrial
 
CM4 Industrial is a computer specially designed for Industrial Control application based on Raspberry Pi Compute Module 4



ED-CM4INDUSTRIAL REV1.0 is an industrial embedded computer based on Raspberry Pi Compute Module 4. The system can be configured by 1GB/2GB/4GB/8GB RAM and 8GB/16GB/32GB EMMC according to different applications, supporting SD card startup.
It provides a variety of industrial communication interfaces and functions, such as RS232, RS485, high-precision ADC, isolated IO input, relay control, real-time clock of battery backup and alarm buzzer. Besides, 1x Ethernet interface with POE function, 1x 10/100M port, 4G/LTE module, external antenna support, certified 2.4/5.8G dual-band WIFI and Bluetooth are also provided. Moreover, ED-CM4INDUSTRIAL supports official 1x 8-megapixel camera, 1x DSI display port and 1x HDMI cable port.
Other features of ED-CM4INDUSTRIAL are also worth mentioning, for example, onboard 32Mb serial Flash is used to store system data, power supply is available in a wide range of 12~18V, and ESD protection is provided for all important interfaces.
The users can add more functions on the board through PCI-e 1x Gen2 interface, the standard 40 pins connector, 2x 4-pin USB interface for internal expansion, 1x TTL electric level RS232 interface, etc. to fully utilize its powerful communication capability to satisfy all kinds of requirement in CM4 Industrial.

FAQ:

1.      Q: What is the difference between V1.0 and V1.1?
A: We found the below bugs on V1.0, those bugs are fixed on V1.1, for the customers who don’t use the below functions, all of other functions and performance are same.
  1. DSI Interface doesn’t properly display
  2. Relay
  3. Silk screen errors on the case
 
2.      Q: What is the operation temperature of CM4 Industrial?
A: The system has been tested at 0~50°C environment, the design uses the metal case to dissipate the heat of CPU, Wireless Module and PMU, the case can offer excellent cooling performance, no need for an additional fan or heatsink.
If you need wider operation temperature, please wait for our industrial version, it will be ready very soon.
