RN2903 – LoRa™ Sub-GHz module

The RN2903 is a fully-certified LoRa™ Sub-GHz, 915 MHz module based on wireless LoRa technology. The RN2903 utilizes a unique spread spectrum modulation within the Sub-GHz band to enable long range, low power, and high network capacity.

The module’s embedded LoRaWAN™ Class A* protocol enables seamless connectivity to the pre-established LoRa network infrastructure. The module is specifically designed for ease of use, which shortens development time, speeding time to market. LoRa technology is ideal for battery-operated sensors and low power applications.

* End-devices of Class A allow for bi-directional communications whereby each end-device’s uplink transmission is followed by two short downlink receive windows.
