The 433/868 MHz RN2483 is a European R&TTE Directive Assessed Radio Module, which can accelerate development time while reducing costs. It combines a small module form factor of just 17.8x26.3x3 mm with 14 GPIOs, providing the flexibility to connect and control a large number of sensors and actuators while taking up very little space.
The RN2483 comes with the LoRaWAN protocol stack, so it can be connected with the established and rapidly expanding LoRa Alliance infrastructure, including both privately managed local area networks (LANs) and telecom-operated public networks, to create Low Power Wide Area Networks (LPWANs) with nationwide coverage. This stack integration will enable the module to be used with any microcontroller that has a UART interface, including hundreds of Microchip's PIC MCUs.In addition, the RN2483 features Microchip's simple ASCII command interface for easy configuration and control.
LoRa technology uses a spread-spectrum base modulation that is capable of demodulation with a 20 dB below noise level. This provides high sensitivity with robust network links, helps improve network efficiency and reduces interference.
The LoRaWAN protocol's star topology also eliminates synchronisation overhead and hops, compared to mesh networks, which reduces power consumption and enables multiple concurrent applications to run on the network. LoRa technology also has a much longer range than other wireless protocols, which enables the RN2483 to operate without repeaters, reducing the total cost of ownership.
The RN2483 has been designed for a broad range of low-data-rate wireless monitoring and control designs. Examples of IoT and M2M applications include: Smart Cities, such as street lights, parking and traffic sensors; Energy Measurement smart meters for electricity, water and gas; and Industrial/Commercial/Home Automation applications such as HVAC controls, smart appliances, security systems and lighting.
