LTE-enabled IoT Gateway Runs Linux on i.MX8M Mini

Eurotech announced a “ReliaGate 10-14” DIN-rail gateway that runs Linux and its ESF IoT stack on an i.MX8M Mini with 2x GbE, DP, isolated serial and DIO, WiFi/BT, optional LTE, and security features including anti-tamper.

The ReliaGate 10-14 “multi-service IoT edge gateway” is a follow-on to Eurotech’s ReliaGate 10-12 and earlier ReliaGate 10-11 gateways, both of which are powered by a Texas Instruments’ Cortex-A8 based Sitara AM3352 SoC. The 10-14 model is a much more substantial upgrade, starting with its more powerful, quad-core, Cortex-A53 i.MX8M Mini SoC. We have covererd plenty of modules and SBCs based on NXP’s Mini, but this is the first Mini-based embedded system we’ve seen.

Like the earlier ReliaGate systems, the ReliaGate 10-14 runs Eurotech Everyware Linux with a Yocto-based SDK with Eclipse tooling and Azul Java support. It also features Eurotech’s Everyware Software Framework (ESF), which was one of the early device-to-cloud IoT aggregation frameworks. This Java/OSGi based-middleware stack offers remote management and supports numerous fieldbus interfaces including Modbus, S7, and OPC UA.

Due to ship in Q2, 2020, the 107 x 85 x 46mm system is smaller than the earlier, 140 x 95 x 45mm ReliaGate models. It also adds more memory and storage, hardware security features, DIN-rail and GbE support, and a display interface, among other features.

Like the previous models, the 10/14 model offers IP40 protection against ingress and supports -20 to 70°C operation. It’s compatible with two expansion modules available with the earlier gateways: the ReliaIO 1012 I/O module and the ReliaLORA 1012 LoRa gateway.

The ReliaGate 10-14 incorporates the quad-core version of NXP’s 14nm-fabricated i.MX8M Mini, which is faster and more power-efficient than the quad -A53 i.MX8M. The Mini offers a 3D GPU but tops out at HD instead of 4K resolution.
