CM4 Sensing is an industrial computer tailored for IoT and data acquisition applications, harnessing the power of the Raspberry Pi Compute Module 4.
This compact system is designed to address thermal challenges often faced by the CPU, wireless module, and PMU, by incorporating structural flexibility and external antennas that enhance wireless communication reliability.
Offering a range of RAM options from 1GB to 8GB and eMMC storage capacities of 8GB, 16GB, or 32GB, the CM4 Sensing is adaptable to various application demands.
For applications requiring substantial data storage, the system supports the use of eMMC for operating system and application data, while a microSD card can be utilized for larger user data storage, providing both capacity and cost-effectiveness.
CM4 Sensing is equipped with a 4G/LTE module, four channels of RS485, one channel each of RS232 and CAN, and a Gigabit Ethernet port.
It also features an alarm buzzer, a battery-powered real-time clock, and supports dual-band WiFi and Bluetooth.
The DSI interface is compatible with the Raspberry Pi's official 7" touch display, and the system can power the display through a 5V/1.5A output.
Additionally, the standard HDMI interface is capable of delivering 4K HD video output.
Two channels of USB 2.0 and one Micro USB 2.0 interface are provided, with the Micro USB port dedicated to updating the system image.
The CM4 Sensing supports a wide range of power inputs from 8V to 28V DC, ensuring flexibility in power source selection.
Its dimensions are slightly larger than the Raspberry Pi 4 Model B, with a heat sink that ensures excellent cooling performance for the CPU, wireless module, and PMU, allowing the system to operate reliably even in high-temperature environments.
