Ultra-low power LoraWAN data communications for IoT

MIKROE has released the LR 11 Click, a new member of the company's 1750-strong mikroBUS-enabled Click board family of compact add-on boards that allows designers to achieve energy-efficient, secure, and reliable, long-distance, bi-directional 915MHz LoraWAN data communications. The board features Ezurio's 453-00139R LoraWAN module which integrates the Silicon Labs EFR32 SoC and the Semtech SX1262 radio. It supports LoRaWAN classes A, B, and C, and operates in the 902-928MHz frequency range with a typical transmit power of up to 22dBm and a communications range of up to 15km. With its extensive regulatory support and certifications, the new Click is ideal for IoT devices, asset tracking, smart home systems, industrial automation, and any application requiring long-range, battery-powered sensor solutions.

Comments Nebojsa Matic, CEO of MIKROE: "A special feature of the LR 11 Click is an additional mikroBUS socket, which expands the board's functionality with peripherals such as sensors and LCDs. Added Click boards can communicate with the onboard 453-00139R module through UART, SPI, or I2C interfaces."

The new Click is fully compatible with the mikroBUS socket and can be used on any host system supporting the mikroBUS standard. It comes with the mikroSDK open-source libraries and example code, offering unparalleled flexibility for evaluation and customisation. This Click board also includes the innovative ClickID feature, which enables the host system to detect and identify it seamlessly and automatically.

The Click package also includes the 868/915MHz FlexDIPOLE antenna, which is matched with the Ezurio 453-00139R module. This combination improves connectivity and functionality, ensuring optimal performance for long-range communication applications.
