Seeeduino LoRaWAN W/GPS is an Arduino development board with LoRaWan protocol and GPS function embedded, through which you can get started quickly to experience LoRa's advantage in the field of IoT. The 4 onboard standard grove connectors allow Seeeduino LoRaWan to connect with hundreds of grove sensors and actuators for Seeeduino conveniently. As a result users are able to be more focus on the application itself without worrying about the compatibility issue between different modules.
