The Unipi Edge E410, a small Raspberry Pi Edge controller based on the Raspberry Pi Compute Module 4 (CM4) is also introduced by the Czech-based company UniPi Technology, which specializes in programmable logic controllers, gateways, and automation hardware. The E410, intended to be used in smart homes, building management systems, industrial automation, and projects based on IoT/IIoT, is a DIN-rail-sized PLC, RTU, IPC, and gateway. It uses the 4-core ARM Cortex-A72 processor of the CM4 and can be configured with up to 32 GB of eMMC storage and 8 GB of RAM.
One of the main points of distinction of the Edge E410 is its flexible I/O choice. The controller has two RS485 connectors, four digital inputs, two digital outputs, five analog inputs and two Ethernet ports with optional LTE, Wi-Fi/Bluetooth and GNSS. This variety of interfaces enables the E410 to be used in building automation, HVAC control, energy management, and industrial monitoring, with the E410 being a powerful Raspberry Pi-based edge controller in a diverse range of automation.
UniPi Edge E410 specifications:
Unipi Edge E410 is designed on the platform of Raspberry Pi CM4 and has a processor with 4 cores: Cortex-A72 with a frequency of up to 1.5GHz. It offers LPDDR4 RAM ranging between 1GB to 8GB with 128Kb NVRAM and eMmc storage options of 8GB, 16GB or 32GB. In the video output, the controller offers a Micro HDMI port with up to 4Kp60. It has networking and wireless capabilities with dual Ethernet ports (1 Gigabit and 1 Fast Ethernet), dual band Wi-Fi, Bluetooth Low Energy and a variety of LTE modules, including Quectel Cat 1, Cat 4 and Cat 1 with GNSS and support of GPS, GLONASS, BeiDou, Galileo, and QZSS. There is also a Micro SIM slot, RP- SMA antenna connectors and two USB 2.0 type-A ports to expand the peripheral.
In case of industrial I/O, E410 has five analogue inputs, four digital inputs, two digital outputs and two RS485 interfaces. Other hardware specifications are the RTC with CR2032 power supply, three user LEDs, hardware watchdog, dedicated service button and TPM 2.0 to ensure secure functionality. The unit is mounted on a hardened aluminum case that is to be installed horizontally as a part of a vertical system and can be connected to a typical 35 mm DIN rail. It has a 24 V DC SELV-rated power supply, operating between -20degC and +60degC, has an IP20 rating, and is 108 x 90 x 56 mm in size and has a total weight of 240 g.
TPM 2.0, a hardware watchdog, memory retention, user LEDs, and a real-time clock are among the features incorporated into the Unipi Edge E410. Unipi’s Base OS, a Debian-based distribution that facilitates custom OS images and Secure Boot configuration during production, is installed on the E410. Additional digital, analog, or communication interfaces can be readily added to a deployment solely due to the design’s ability to accommodate expansion with the aid of Unipi’s xS module line. The company’s Knowledge Base additionally provides more firmware images and manuals.
The Unipi Edge E410 (1 GB RAM, 8 GB eMMC) is priced at $473.47, and the company also offers custom configurations with different RAM/eMMC options and optional GNSS, LTE, and Wi-Fi/Bluetooth modules. Pricing for the series starts at $473.47 for the Edge E410, while the Edge E413 with the same configuration costs $408.27, and the newly listed Edge E411 is the most affordable at $347.39 (or $287.10 excluding VAT).
