Introduction

CM4 Sensing is an industrial computer designed for IoT & Data Acquisition applications based on
Raspberry Pi Compute Module 4 (CM4 for short). It makes full use of the structural flexibility of CM4 to solve the heat dissipation problem of the CPU, wireless module and PMU. The external antenna improves the reliability of wireless communication.

The system can be configured into 1GB/2GB/4GB/8GB RAM and 8GB/16GB/32GB eMMC, 2.4/5.8G
dual-band WiFi and Bluetooth (optional) according to different applications, and it supports an external antenna.

For application scenarios that require large data storage capacity, users can use eMMC to install the
operating system and store the application data, at the same time, the user can use an SD card to store large user data, compared to the built-in eMMC memory, an SD card can offer a larger capacity and its cost is more effective.

CM4 Sensing provides 4G/LTE module, 4 channels RS485,1 channel RS232, 1 channel CAN, 1 channel
Gigabit Ethernet port, alarm buzzer, battery-powered real-time clock. The DSI interface of CM4 Sensing is fully compatible with Raspberry Pi4 Model B and supports Raspberry Pi’s official 7″ touch display. A 5V/1.5A power output provides the power for Pi Display, the Standard HDMI interface can output 4K HD video.CM4 Sensing provides 2 channels USB2.0 and 1 channel Micro USB2.0 interfaces, and Micro USB interface is used to update the system image. The system supports +12V~18VDC power input, the dimension of CM4 Sensing is 103*73*32mm, which is slightly larger than Pi4 Model B. The connectors come out from the front and back end and a 103*73mm*5mm heat sink provide excellent cooling performance for the CPU, wireless module and PMU, the whole system can work reliably in a high-temperature environment.Based on our real testing in the lab, CM4 Sensing can work reliably at ambient temperature of -25~60°C.Four M2.5 screw holes are reserved at the case bottom of the CM4 Sensing, which is convenient for users to install the CM4 Sensing on other equipment, it also
supports DIN rail mounting.
