+This **M5GO IOT Kit** is a multi-Unit feast with 6 M5units  inside (ENV II, IR, RGB, PIR, ANGLE, HUB). Just like other M5Stack development kit, M5GO is powered by ESP32.
 
 Every M5stack development kit can be programmed through Arduino IDE, WebIDE UIFlow, Micropython, and Blockly, simplifying the development process for those requiring 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.
