AAEON SRG-CM4: A RISC gateway board with dual Gigabit Ethernet Featuring Raspberry Pi CM4 for Industrial Applications

AAEON has recently launched the SRG-CM4, a RISC gateway board featuring a Broadcom BCM2711 quad-core Cortex-A72 SoC running at 1.5 GHz. This compute module 4 (CM4) is specially designed for industrial and IoT applications, offering high-performance and flexible connectivity options. The board supports up to 8 GB of LPDDR4 memory, eMMC 5.1 storage (8 GB to 16 GB), and provides dual Gigabit Ethernet ports, multiple USB 2.0 ports, and RS-232/422/485 serial interfaces, with RS-485 featuring isolation. Additional interfaces with isolation include HDMI, CAN 2.0 A/B, TPM 2.0, and DI/DO. It has a wide operating temperature range of -20°C to 70°C, supports a 9V to 36V power input, and can be mounted using wall or DIN rail kits. It supports the Raspberry Pi Desktop OS and Debian 11, making it a flexible and reliable choice for embedded systems and edge computing deployments.

Additionally, the board comes with a Real-Time Clock (RTC) feature, powered by a 3V CR2032H lithium battery. You can maintain accurate time even when powered off, making it useful for tasks like scheduling and logging.

Previously we have covered some Raspberry Pi-based Boards including the Luckfox Core3566, the CM Hunter, the Piunora Carrier board, and many more. Therefore, feel free to check those out if you are interested in the topic.

Moreover, the SRG-CM4 is compatible with Raspberry Pi OS and Debian 11, so you can access various open-source software, development tools, and libraries. Although, this makes it a flexible choice for creating industrial solutions in areas like manufacturing. It seems that it has wall mounting and optional DIN rail mounting, ensuring seamless integration into factory or kiosk environments.

The SRG-CM4 package includes the main SRG-CM4 board and a 2-pin 3.81mm power terminal block with a lock, suitable for wires with an AWG rating of 28 to 14. However, the power adapter is not part of the standard package. If you need a power adapter, it can be added to your order separately using the following link at $9.00.

The SRG-CM4 is available at AAEON’s store for $217.00. Further information, a datasheet, and a manual are available on the company’s official product page.
