DescriptionDocumentsDatasheet of ED-CM4SEN-2023-01-09-ENGCM4 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 USB 2.0 and 1 channel Micro USB 2.0 interfaces, and Micro USB interface is used to update the system image.The system supports 8V~28VDC* 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 and wall mounting.#Hardware Specification#Raspberry Pi CM4 InsideBroadcom BCM2711Quad-core, Cortex-A72, 1.5GHz ARM v8 64-bit CPUSupport H.264, H.265 decoding, Support 4Kp60 video playSupport H.264 encodingSupport OpenGL EL 3.0DDRLPDDR4, up to 3200MT/s1GB | 2GB | 4GB | 8GBDual Storage8GB | 16GB | 32GB eMMCmicro-SD Card for Data storage#Dual StorageeMMC for rootfs1x microSD Slot (for data storage)#Display1x HDMI Type A1x DSI, Support Raspberry Pi official 7″ Touch Display1x HDMI FPC#Wired Interfaces1x 10/100M/1000Mbps Ethernet2x USB 2.0 Type A1x Micro USB 2.0(for eMMC Flashing and some USB Device Applications)#Wireless1x 4G/LTE module(optional)1x 2.4G/5.8G WiFi, IEEE 802.11 b/g/n/ac1x Bluetooth 5.0, Support BLEOptional certified WiFi/BT External antenna with Raspberry Pi CM4#Industrial Interfaces4x RS4851x CAN1x RS2321x RTC with battery1x LED for Power Indicator1x LED for System status Indicator1x Buzzer#Expansion InterfacesMini PCIe slot with 1-lane PCIe Gen2 and 1x USB 2.0 Host#Power In8~28V DC Power Jack，Optional Phoenix terminal for power in#Operating Temperature-25 ~ 60°C#Dimension103 mm(L) x 73 mm(W) x 32mm(H)#Software#Raspberry Pi EcosystemCompatible with Origin Raspberry Pi OS, support 32-bit and 64-bit OSSupport install and update BSP with apt-getSupport Kernel and OS UpgradePre-installed Os in eMMC, ready-to-use#Interface Diagram#Top#Bottom
