AAEON SRG-CM4 IoT gateway features Raspberry Pi CM4 SoM for industrial applications

AAEON SRG-CM4 is an IoT gateway based on the Raspberry Pi Compute Module 4 (CM4) with 1GB to 8GB of RAM and 8GB to 32GB of eMMC storage, all powered by the Broadcom BCM2711 quad-core Cortex-A72 SoC. The gateway features a modular chassis, maintaining the compact size and industrial-grade features typical of AAEON’s edge gateway products, making it ideal for various embedded applications.

In terms of connectivity, the SRG-CM4 offers two switchable serial ports supporting RS-232/422/485, with an optional isolated RS-485 port, CAN 2.0 A/B, and two isolated DI/DO. Additional interfaces include two Gigabit Ethernet RJ45 ports, two USB 2.0 ports, and an HDMI 1.4 video output. The device operates within a wide temperature range of -20°C to 70°C and supports a DC 9V to 36V power input, ensuring reliability in industrial environments.

We previously covered the reComputer R1025-10, a Raspberry Pi CM4-based DIN Rail industrial gateway with optional wireless modules, including 4G, LoRa, Zigbee, and Wi-Fi/BLE. Other Raspberry Pi CM4-based gateways we’ve featured include the WisGate Connect, the EDATEC ED-GWL2110 IP24-rated outdoor gateway, the Home Assistant Yellow automation gateway, and the iModGATE-AI for failure monitoring and predictive maintenance of IoT installations. Feel free to explore these products if you’re interested.
