Würth Elektronik launches Thetis-I, a ready-to-use radio module for Wirepas mesh networks. Thetis-I is the perfect solution for IoT device manufacturers. Networks with technology from Wirepas, the Finnish software provider, are self-healing and freely scalable. Each device with a Thetis-I radio module can also act as a router which means no further infrastructure is required for mesh communication. Würth Elektronik offers developers the Thetis-I Evaluation Kit. It contains an evaluation board, a USB radio stick, and three sensor nodes. Thanks to the tailored Wirepas Commander software, this kit can be operated and configured directly via a PC.

Thetis-I is based on the Nordic nRF52840 chipset and the proven proprietary 2.4 GHz radio module. The radio module, optimized for Wirepas networks, is extremely energy-saving and offers the choice between low-energy and low-latency modes. The module, which measures just 8×12×2 mm, can be configured remotely using the freely available Wirepas Commander software. It supports authentication and encryption, stand-alone or host-controlled operation. The wide range of potential applications can be tested using the Evaluation Kit. Wirepas technology enables easy connection to well-known cloud platforms. The slim evaluation board allows a controller board to be connected for developing applications. A battery-powered sensor board equipped with the versatile WSEN-PADS pressure sensor and the WSEN-HIDS humidity sensor readily provides an application example for a mesh network.

Thetis-I and the Evaluation Kit are now available from stock without minimum order quantities. Individualized firmware versions can also be supplied on request.

Wirepas is a leading IoT connectivity company focused on large-scale, low-power IoT networks. Together with its steadily growing ecosystem and partners, it raises efficiency in applications such as Smart Buildings, Smart Factories and Smart Logistics. Wirepas Mesh—continuously evolving IoT connectivity software—is the only technology allowing any number of devices, even battery-powered ones, to create a network autonomously. In addition, various device types are interoperable in a network. This mesh network provides large-area wireless coverage, but can also reliably and autonomously manage a high density of devices (up to a thousand devices per cubic meter). Wirepas serves its customers around the world with offices in Australia, Brazil, Finland, France, Germany, India, South Korea and the United States. More information at
