M5Core GRAY

Description

M5Core GRAY is a development kit based on ESP32 chip composed of a gray M5Core and a Bottom Base board. You can even program The M5Core GRAY through Blockly, Arduino or MicroPython.

The M5Core GRAY equips ESP32 with everything necessary to program. It also features a MEMS Chip(MPU9250), and a TFT LCD, so you can create a 3D remote gesture controller, a simple "Leap Motion" via M5Core GRAY in a day in stead of couple weeks and so on.

This is 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.
