  • LoRa 2 Click - MikroElektronika Microchip RN2903 915MHz LoRa Modem

    LoRa 2 click carries Microchip’s RN2903 915 MHz Radio Modem compliant with regulations for use in the United StatesCanadaAustralia and New Zealand. The click is designed to use either a 3.3V or a 5V power supply. It communicates with the target microcontroller over a UART interface (TXD, RXD, CTS) with the addition of a Reset pin (RST) and RTS pin. 

    NOTE: The antenna is sold separately.

    RN2903 module

    The RN2903 module has a specified range of >15km in rural and suburban settings, and >5km coverage in urban areas.

    A LoRaWAN™ Class A protocol stack is embedded (bidirectional end devices), as well as an ASCII command interface accessible through UART. The high receiver sensitivity can go down to -146 dBm.


    LoRaWAN™ or Low Power Wide Area Network is a wireless technology developed to enable low data rate communications over long distances, mainly for IoT applications and sensors.

    The architecture for this network is usually arranged in a star-of-stars topology. A gateway relays messages between end-devices (for example, battery operated devices in home automation) and a central core network server.
