Product Overview

The DM164139 from Microchip is a 915MHz RN2903 LoRa technology mote. The RN2903 LoRa mote is a LoRaWAN class A end device based on the RN2903 LoRa modem. As a standalone battery powered node, the mote provides a convenient platform to quickly demonstrate the long range capabilities of the modem as well as to verify interoperability when connecting to LoRaWAN v1.0 compliant gateways and infrastructure. The mote includes light and temperature sensors to generate data which are transmitted either on a fixed schedule or initiated by a button press. An LCD display provides feedback on connection status, sensor values and downlink data or acknowledgements. A standard USB interface is provided for connection to a host computer, providing a bridge to the UART interface of the RN2903 modem. As with all Microchip RN family of products, this enables rapid setup and control of the on-board LoRaWAN protocol stack using the high level ASCII command set.
