LoRa (short for long range) is a kind of spread spectrum modulation evolved from chirp spread spectrum (CSS) technology. LoRaWAN is the LoRa Alliance’s network system architecture and communication protocol definition for LoRa. LoRaWAN is a Media Access Control (MAC) layer protocol that allows LoRa to be used in a broader range of applications. The LoRa Alliance specifies the network’s networking layer and system architecture.
Maduino Zero LoRaWan is a solution based on the ATSAMD21G18 MCU and the Ra-07H LoRaWAN module. The Ra-07H LoRaWAN module is based on the ASR6501 chip, which includes a LoRa radio transceiver, a LoRa modem, and a 32-bit RISC MCU that supports LoRa modulation mode and (G) FSK modulation mode. By connecting a LoRaWAN Gateway, Maduino LoRaWan operates as a LoRaWAN node, transmitting and receiving local data to the network. Users may simply prototype LoRaWAN solutions using this module in a matter of hours.
Maduino LoRaWan is Arduino-compatible, and simple examples of communication with TTN are given. It should be noted that a LoRaWAN router is required for LoRaWAN communication, with complete usage and setup instructions available on the Wiki.
