Overview
|
- 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 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 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, users can use SD card to store large user data, compare to the built-in eMMC memory, SD card can offer 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 are fully compatible with Raspberry Pi4 Model B, supports Raspberry Pi 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 8V~28V DC* power input, the dimension of CM4 Sensing is 103*73*32mm, which is slightly larger than Pi4 Model B. The connectors come out from front and back end, a 103*73mm*5mm heat sink provides excellent cooling performance for 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. - Certified with CE/FCC. |

FAQ
|
1.How to install CM4 Sensing?
There are 4 screw-holes(M2.5) on the bottom casing of the device. Fix the CM4Sensing into necessary device with these holes. Besides, CM4Sensing support DIN rail mounting.
|
|
2.How to update the system image?
Use the Micro USB2.0 port at the internal circuit board to update system image of CM4 sensing.
|
|
3.Whether CM4 sensing can boot in micro SD card?
No, micro SD card only acts as data storage. Operation system shall be installed in eMMC.
|
|
4.What does different LED color mean?
Red indicates for power supply and green indicates for system status.
|
|
5.Which types are Power Adapter supporting?
12V 2A power adapter with EU, US, AU and UK plugs available.
|
|
6.What is the power supply that powers the RTC?
CR1220 coin battery
|
|
