Wireless Transmitter 868Mhz Lora Shield for Leonardo, UNO, Mega2560, Duemilanove, Due
The LoRa Shield, designed in the Arduino shield form factor and built on an open-source library, is a powerful long-range transceiver with exceptional capabilities. It enables users to transmit data over vast distances at low data rates, making it ideal for applications that require wide coverage. The shield offers ultra-long-range spread spectrum communication, superior interference immunity, and low current consumption.
Powered by the RFM95W module, the LoRa Shield is specifically designed for professional wireless sensor network applications, including irrigation systems, smart metering, smart cities, smartphone detection, and building automation. Utilizing Hope RF’s patented LoRa™ modulation technology, the shield delivers impressive sensitivity of over -148 dBm using cost-effective components. Its integrated +20 dBm power amplifier ensures an industry-leading link budget, making it perfect for applications where range and robustness are critical.
LoRa™ modulation provides distinct advantages over traditional communication methods, particularly in blocking and selectivity. This effectively resolves the common trade-offs between range, interference immunity, and energy efficiency. The shield also supports high-performance (G)FSK modes, ideal for systems like WMBus and IEEE802.15.4g. This results in exceptional phase noise, selectivity, receiver linearity, and IIP3, while significantly reducing current consumption compared to competing devices—enhancing efficiency and extending battery life across a wide range of applications.
