Introduction

RAK831 is a RF front end of a LoRa™ gateway. It is able to receive on different frequency channels at the same time and is able to demodulate the LoRa™ signal without knowledge of the used spreading factor of the sending node.

With the compact design, this is a ideal modular products to help you realize the whole Lora system development. With the USB-SPI converter module FT2232, you can quickly to make the software development in your PC. But also, you can integrate the concentrator module to your production product to realize the Lora gateway function. This is very economic way to address for a huge variety of applications like Smart Grid, Intelligent Farm, intelligent Farm and Other IoT applications.

The RAK831 needs a host system like Raspberry Pi or WisAP(OpenWRT based) or WisCam for proper operation. The host processor can be a PC or MCU that will be connected to RAK831 via USB or SPI.
