LoRa (short term for long range) is a spread spectrum modulation technique derived from chirp spread spectrum (CSS) technology. LoRaWAN is the network system architecture and communication protocol specification for LoRa, developed by the LoRa Alliance. LoRaWAN is a Media Access Control (MAC) layer protocol that enables LoRa in wider applications. The LoRa Alliance defines the networking layer and the system architecture for the network.

Maduino Zero LoRaWan is a solution based on ATSAMD21G18 MCU and LoRaWAN module Ra-07H. The LoRaWAN module Ra-07H is based on the ASR6501 chip, it integrated the LoRa radio transceiver, LoRa modem, and 32-bit RISC MCU, to support LoRa modulation mode and (G) FSK modulation mode. Maduino LoRaWan acts as a LoRaWAN node to transmit/receive the local data to the network by connecting LoRaWAN Gateway. With this module, users are easy to prototype LoRaWAN projects easily in a few hours.

Updates on 2023/3/8: The latest Maudino Zero LoraWAN 2.0 has been updated to the RA0-08H, which is based on ASR6601, with better performance on power consumption.

Maduino LoRaWan is compatible with Arduino and basic demos communicating with TTN are provided. Note that for LoRaWAN communication, a LoRaWAN router is needed, detailed usage& setup as in the Wiki.
