Description

M5GO-Lite is a lightweight STEM education kit in the M5Stack development kit series. The M5GO Lite provides 1 ENV Unit (for environmental temperature, humidity, and pressure detection). Compared to the "M5GO IoT Kit," it has reduced the number of Units and accessories, offering more flexibility in configuration. For users who want to purchase other Units or conduct small STEM courses, the M5GO-Lite is a great choice.

It offers an online version of the WebIDE UIFlow programming platform, allowing students to experience the power of IoT through network-based program deployment. It supports multiple programming methods, helping students gradually transition from graphical programming to understanding actual code.

As a kit designed specifically for STEM education, M5GO aims to make learning both educational and fun, giving students a sense of accomplishment as they turn their ideas into reality. It allows students to freely explore the world of engineering, create their own IoT products, and integrate creative ideas into real-life applications.

USB Driver

Click the link below to download the driver that matches the operating system. There are currently two driver chip versions (CP210X/CH9102). Please download the corresponding driver compressed package according to the version you are using. After decompressing the compressed package, select the installation package corresponding to the number of operating systems to install. (If you are not sure of the USB chip used by your device, you can install both drivers at the same time. During the installation process of CH9102_VCP_SER_MacOS v1.7, an error may occur, but the installation is actually completed, just ignore it.)
