The Field-Proven Data & Connectivity Unit
The TCG-4 is a field-proven performance unit within the TCG family, combining reliable hardware, strong connectivity and robust industrial design. Equipped with 4G/LTE, WiFi (2.4/5 GHz), Bluetooth 4.2 and a dedicated GNSS receiver supporting GPS, GLONASS, BeiDou and Galileo, it enables stable data transfer, precise positioning and modern IoT use cases. The NXP i.MX 6UltraLite processor, up to 1 GB RAM and 32 GB eMMC provide the power needed for edge computing, preprocessing and local analytics directly on the machine.
Running on Embedded Linux, the TCG-4 offers an open development environment with libraries, toolchains and connectivity frameworks. This allows fast implementation of custom applications and seamless integration with cloud systems. Cloud connectivity can be achieved using STW’s off-the-shelf solutions, STW-hosted platforms or fully customer-managed servers. MQTT connectors and detailed integration guides support flexible service architectures and fully tailored digital workflows.
Configurable Hardware Variants and Comprehensive Connectivity
With its configurable hardware design and multiple available variants, the TCG-4 can be adapted precisely to application needs. Options include different memory sizes, antenna configurations, GNSS setups, and interface extensions. Up to four CAN buses, RS232/RS485, Ethernet, Single Pair Ethernet (SPE), USB, multifunctional analog and digital I/Os and several wake-up functions enable seamless integration into complex machine architectures. Optional galvanic isolation, USB-OTG and customer-specific configurations provide additional design freedom.
The device supports global 4G/3G/2G standards, ensuring reliable operation across regions and networks. Integrated sensors such as temperature and 3-axis acceleration enhance diagnostics and machine intelligence. Thanks to free programmability, WiFi mesh capabilities, Bluetooth Low Energy and open communication protocols, IoT and M2M solutions can be realized efficiently and cost-effectively.
Secure, Robust and Future-Ready – the Digital Gatekeeper of the Machine
Fully form-fit-function compatible with previous TCG generations, the TCG-4 protects long-term investments while enabling modern connectivity. It complies with demanding industry standards for automotive, agricultural and construction machinery. Designed as a secure digital gateway, the TCG-4 follows state-of-the-art cyber security principles and meets the latest regulatory requirements, including the EU Cyber Resilience Act.
With its durable hardware, flexible connectivity, open cloud integration and strong security foundation, the TCG-4 acts as the digital gatekeeper of the machine and provides a reliable basis for connected products and data-driven business models.
