+**The M5Stack BASIC** is a black development kit based on **ESP32** chip composed of a black M5Core and a Bottom Base board. You can even program The M5Stack BASIC through Blockly, Arduino or MicroPython. The black core is a basic kit and **it does not own any MEMS chip(like MPU9250...)**.

 The a Bottom board on the back of M5Core. It's designed for expanding gpio on M-Bus besides I2S Pins(GPIO0, GPIO12, GPIO13, GPIO15, GPIO34)for DIY. Each gpio on M-Bus is expanded as pin and port for convenience and flexibility.
