Discontinued Product: This is the original RNode design. I am no longer producing it, but this page is still available for reference purposes. Please have a look at the new Handheld RNode instead.

RNode is an integrated, long-range data-radio module, that connects to a host via USB or UART and uses raw LoRa modulation in a variety of frequency bands.

Or in short: A very flexible LoRa-based communication device. It's probably the most flexible and easy to use LoRa device you can get your hands on.

RNode can functions as a:

  • LoRa interface for any device with a USB or serial port
  • General purpose long-range data radio
  • Packet sniffer for LoRa networks
  • LoRa development board
  • A LoRa-based KISS-compatible TNC
  • Network adapter for RNS
  • A flexible platform for experiementing with LoRa technology

RNode is controlled by a powerful ATmega1284p MCU, and is fully Arduino compatible. You can use the included firmware, or it can be programmed any way you like, either from the Arduino IDE, or using any of the available tools for AVR development. The included firmware can also be edited and compiled directly from the Arduino IDE.

RNode comes mounted in a case, as shown in the photos, but can be removed from the case if you require access to the IO pins on the board. To remove an RNode from it's case, simply hold the part of the case close to the antenna connector, and press the antenna connector against a hard object, like a table. The bottom part of the case (where the USB connector is situated) will pop off, and you will be able to slide the unit out of its case.

RNode does not come with an included antenna, so if you don't already have one, be sure to add a suitable one to your order. The device should never be used without an antenna attached.
