German firm Würth Elektronik has launched a slim, low power consumption and long-range radio module for IoT applications.

The Daphnis-I transceiver, based on STM’s 32WLE5CCU6 chip, works with the LoRaWan 1.0.4 protocol. This IoT wireless protocol in the EU868 frequency band allows communication with devices more than 10km away from the gateway.

Measuring 15 by 16 by 3mm, the module fits into size constrained applications. Power consumption is 63.9nA in sleep mode, making it suitable for battery-powered IoT applications.

For application developers there is a tailored evaluation kit, and Smart Commander management software with gui.

Daphnis-I supports LoRaWan classes A, B and C, which means the module can receive data in response to its transmissions, either time-controlled or with a permanently open download-receive window. The module is controlled via a uart interface using an AT command set. The module can register to network (activation) with either OTAA or ABP activation. For connecting the antenna, there is a choice between the UMRF connector and the RF pin. The output power is 13.4dBm.

Applications include smart homes and cities, crop and livestock monitoring, infrastructure monitoring, security systems, logistics and transportation management, and smart factory applications and Industry 4.0. By optimising the wireless module to reduce its energy requirement, even battery-operated devices with low maintenance can be designed.

The Daphnis-I wireless module (www.we-online.com/en/components/products/DAPHNIS-I) is available from stock without minimum order quantities.

Würth Elektronik makes electronic and electromechanical components for the electronics industry. It is one of the largest European manufacturers of passive components and is active in 50 countries. Production sites in Europe, Asia and North America supply customers worldwide.

The product range includes EMC components, inductors, transformers, RF components, varistors, capacitors, resistors, quartz crystals, oscillators, power modules, wireless power transfer, LEDs, sensors, radio modules, connectors, power supply elements, switches, push-buttons, connection technology, fuse holders and wireless data transmission.
