Würth Elektronik is expanding its range of FeatherWing development boards with the addition of the Daphnis-I FeatherWing Board. This new board features the energy-efficient Daphnis-I radio module, which operates using the LoRaWAN 1.0.4 protocol in the EU868 frequency band. This protocol allows devices to communicate with a gateway located over ten kilometers away, making it ideal for a variety of IoT applications such as smart factories, smart homes, and smart cities, as well as monitoring tasks in agriculture and logistics.
The Adafruit Feather form factor offers developers the ability to seamlessly combine Würth Elektronik’s FeatherWings with compatible boards from other manufacturers. With the Daphnis-I FeatherWing, Würth Elektronik is now providing power-saving LoRaWAN technology alongside its other wireless solutions. The radio module on the Feather board, based on the STM32WLE5CCU6 chip, boasts low current consumption of just 63.9 nA in sleep mode, making it perfect for battery-powered IoT applications. The FeatherWing comes with the external 868 MHz Hyperion-I antenna and a UMRF-to-SMA RF cable.
The LoRaWAN architecture features a star topology, with end devices communicating with gateways that forward data packets to a LoRaWAN server, which then communicates with the application server. All communication is secured with 128-bit AES encryption. The Daphnis-I FeatherWing supports LoRaWAN classes A, B, and C, allowing for different methods of data transmission and reception. The radio module is controlled via a UART interface using an AT command set and can log on to the network using either OTAA or ABP methods. Würth Elektronik provides an evaluation kit for the Daphnis-I module, along with a PC tool and software development kit for its FeatherWing portfolio.
The Daphnis-I FeatherWing is now available for purchase without a minimum order quantity. Developers can access Würth Elektronik’s GitHub repository for examples and resources related to the Daphnis-I module, including secure connections with LoRaWAN network servers and data transmission to various cloud platforms like TTN, AWS, Microsoft Azure IoT Hub, and Kaa IoT.
