Description

M5GO Lite is a light pack of M5GO kit, instead of having 6 M5units, M5GO-Lite provides 1 ENV + accessories and the same M5 controller as M5GO. M5GO-Lite is also designed for STEM education. M5GO controller itself is already a full-feathered, highly integrated, upgraded development board(which) provides plenty of hardware resources, such as LCD screen, speaker, Led bar, 16M flash, microphone and more. Light(Last) but not least.

all M5stack development board can be programmed by using Arduino IDE, WebIDE UIFlow, Micropython and Blockly. It greatly simplifies the development process for those projects which require a joint hardware and software solution. Not only does M5stack have far-reaching IoT applications in industry, agriculture, and home, but it also empowers students to learn to code in STEM classrooms.

Power on/off:
Power on: click the red power button on the left

Driver Installation

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.)
