## 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

* Power off: Quickly double-click the red power button on the left
