Microchip announces an addition to its LoRa® technology product line. The new RN2903 wireless modem works with North American Low-Power Wide-Area Networks (LPWAN) and is FCC certified for use in the 915 MHz band. The RN2903 modem is designed to be an efficient way to add long-range LoRaWAN network capability to any embedded design by integrating a proven LoRaWAN™ protocol stack running on a low-power PIC® microcontroller, along with the LoRa radio and embedded antenna matching circuit.
Driven by the LoRa Alliance, LoRa technology is able to achieve a range of up to 10 miles and 10-year battery life. The technology targets low data rates and low duty-cycle applications such as energy metering, location tracking, utility infrastructure monitoring and control, smart city and agriculture. Although predominantly used for the uplink of sensor data, bidirectional communications allow real-time acknowledgement of mission-critical data and downlink control of remote actuator nodes.
The RN2903 is designed to be easy to adopt, which minimises research and development investment and speeds time-to-market. The simple ASCII-over-UART interface can be controlled by any embedded system, even down to a tiny, eight-pin PIC12 MCU, and the embedded antenna matching circuits and FCC modular certification require minimal radio expertise.
The RN2903 is fully available now. The ‘Mote’ development boards (DM164139) are also available now, priced at $69.99 each.
