The ED-CM4IO is an industrial computer based on Raspberry Pi Compute Module 4 & IO board. The system can be configured with 1GB/2GB/4GB/8GB RAM and 8GB/16GB/32GB EMMC according to different applications, and also support SD card boot.

ED-CM4IO supports 2 standard HDMI connectors with 4K high-definition output, 2 channels USB2.0, 1
channel Gigabit Ethernet, 2x 4-channel CSI and 2x 4-channel DSI interfaces, which support Raspberry
official cameras and display through the adapter cable.
ED-CM4IO supports 2.4G/5.8G dual-band WiFi and Bluetooth 5.0, with Raspberry Pi certified ED-CM4IO supports 2.4G/5.8G dual-band WiFi and Bluetooth 5.0, with Raspberry Pi certified WiFi/Bluetooth antenna.

The system on or off can be controlled by a green button, and a PWM-controlled fan automatically manages the temperature of the CPU, when the CPU is getting hotter, the speed of the fan will increase and remove the heat from the CPU, PMU and Wireless Module.

When the temperature of the CPU is reduced, the fan will operate in quiet mode at a very slow speed.
ED-CM4IO provides standard 40-pin signal expansion, users can expand PCI-e devices through PCI-e 1x Gen2 socket.

Onboard RTC can wake up the CPU Onboard RTC can wake up the CPU during shutdown mode.
