Advancing IoT in the lab: Next generation Gateway-Module for laboratory device integration

This article introduces the next generation of the Gateway-Module, which is designed to simplify experimental setups and to further advance digitization. Based on the innovative work of Porr et al. in 2020, the Gateway-Module-v3 replaces the single board computer (SBC) with a Phytec i.MX 8M Plus (phycore-imx8mp) System on Module (SoM). This upgrade significantly reduces the physical size of the module to a compact 5.4 cm width, length, and height. Gateway-Module-v3 seamlessly integrates with standards such as Standard in Laboratory Automation (SiLA 2) and Open Platform Communication Unified Architecture (OPC-UA), advancing the digitization and efficiency of laboratory operations. At the center of its innovation is the tty2eth management module, which provides robust remote monitoring and maintenance using SSH and Prometheus metrics to ensure that experiments run smoothly even from remote locations. The Gateway-Module-v3 offers a wide range of connectivity options, including GPIO, USB and serial ports, making it adaptable to a variety of applications. Rigorous stress testing has confirmed its reliability and performance under demanding conditions, highlighting the suitability for both laboratory and remote scenarios. With its advanced functionality and connectivity, the Gateway-Module-v3 is ready to support researchers, advance their work, and will serve as a fundamental resource for current and future needs.
