M5stack Technology M5Paper Touchable Ink Screen Controller Device
Overview
M5 Paper is a touchable ink screen controller device. This document will demonstrate how to use the device to test basic WIFI and Bluetooth functions.
Development environment
Arduino IDE
Go to https://www.arduino.cc/en/main/software to download the Arduino IDE
corresponding to your operating system and install it. 
Open the Arduino IDE and add the management address of the M5Stack board to the preferences. https://m5stack.oss-cn- shenzhen.aliyuncs.com/resource/arduino/package_m5stack_index.json
Search for “M5Stack” in the board management and download it.
WiFi
Use the official WIFI scanning case provided by ESP32 in the Example list to
test.
After uploading the program to the development board, open the serial monitor
to view the WiFi scan results.
Bluetooth
Demonstrate how to use classic Bluetooth to send messages through Bluetooth
and transmit them to the serial port for printing.
After uploading the program to the development board, use any Bluetooth serial debugging tool to pair and connect, and send messages. (The following will use the mobile phone Bluetooth serial port debugging app for demonstration).
After the debugging tool sends a message, the device will receive the message
and print it to the serial port.
Overview
M5 Paper is a touchable ink screen controller device, the controller adopts ESP32-D0WD. An electronic ink screen with a resolution of 540*960 @4.7″ is embedded on the front, supporting 16-level grayscale display. With GT911 capacitive touch panel, it supports two-point touch and multiple gesture operations. Integrated dial wheel encoder, SD card slot, and physical buttons. An additional FM24C02 storage chip (256KB-EEPROM) is mounted for power-off storage of data. Built-in 1150mAh lithium battery, combined with the internal RTC (BM8563) can achieve sleep and wake-up functions, The device provides strong endurance. The opening of 3 sets of HY2.0-4P peripheral interfaces can expand more sensor devices.
