1. Introduction

1.1 Overview

MS20 is an Open Source Linux box designed as a generic IoT Gateway for different IoT applications.

MS20 is equipped with a  Quad-core Cortex-A7 1.2Ghz CPU, 512MB RAM, 4GB eMMC memory, and SD card slot. MS20 supports different kinds of network connections such as Ethernet, WiFi, and an optional 4G connection. There are internal GPIOs and USB interface inside MS20 for developers to develop customized modules for their IoT application.

The OS running in MS20 is Armbian( a embedded version of Debian), which is easy to maintain. The OS is completely open-source for users to develop different kinds of software. There are also some very useful pre-load software such as Web-UI, Node-Red, remote management, network management, and auto-update for the quick start of deployment and maintenance.
