1. Introduction

1.1 Purpose& Description

Dusun Pi3 Model C is a full 8-channel outdoor Gateway, based on the LoRaWAN protocol, with built-in Ethernet connectivity for a straightforward setup. Additionally, there is an onboard Wi-Fi setup (supporting 2.4 GHz/5GHz Wi-Fi) that allows it to be easily configured via the default Wi-Fi AP mode. With its industrial-grade components, it achieves a high standard of reliability.
