Device Overview

Summary

The RN2903 is a fully-certified 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 any LoRaWAN compliant network infrastructure, whether public or privately deployed.  The module is specifically designed for ease of use, which shortens development time and speeds time to market.  LoRa technology is ideal for battery-operated sensors and low power applications such as IoT, M2M, Smart City, Sensor networks, Industrial automation, and more.

Microchip's complimentary and confidential Wireless Check online design review service is available for customers who have selected our products for their application design-in*.
*The online design review service is subject to Microchip's Program Terms and Conditions and requires a myMicrochip account.
