Würth Elektronik Introduces Daphnis-I LoRaWAN Module for IoT Applications

The transceiver, based on the STM32WLE5CCU6 chip, works with the LoRaWAN^® (Long Range Wide Area Network) 1.0.4 protocol. This IoT wireless protocol in the EU868 frequency band allows communication with devices more than ten kilometers away from the gateway. Measuring just 15 × 16 × 3 mm, the Daphnis-I module also fits into size constraints IoT applications. Daphnis-I stands out with its remarkably low power consumption of just 63.9 nA in sleep mode, making it the perfect fit for battery-powered IoT applications. Würth Elektronik offers application developers a tailored evaluation kit, and Smart Commander, a convenient management software with GUI.

Daphnis-I supports LoRaWAN^® class A, B and C, which means that 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 easy-to-use AT command set. The Daphnis-I can register to network (activation) with either OTAA or ABP method of activation. For connecting the antenna, there is a choice between the UMRF connector and the RF pin. The output power is 13.4 dBm.

For decentralized IoT applications
The application options vary widely: IoT solutions for smart homes and smart cities, crop and livestock monitoring in agriculture, infrastructure monitoring, security systems, logistics and transportation management, or smart factory applications and Industry 4.0. By optimizing the wireless module to minimize its energy requirement, even battery-operated devices with low maintenance can be designed.
