Microchip RN2903 RF Transceiver Module
Microchip Technology's RN2903 is a fully certified, 915 MHz module based on wireless LoRa technology made to provide an easy to use, low-power solution for long range wireless data transmission. The RN2903 has the complete LoRaWAN™ protocol stack on the modem and is configurable with simple ASCII commands through the UART, greatly reducing development time. Additionally, it combines a compact form factor (17.8 × 26.7 × 3 mm) with fourteen GPIOs; providing the flexibility to connect and control a large number of sensors and actuators while taking up very little space. With its scalability, robust communication, mobility, and the ability to operate in harsh outdoor environments, the RN2903 is well suited for a broad range of low-data-rate wireless monitoring and control designs.
