Description

M5Paper COMM it's a Commemorative Edition device with a touchable E-ink display from M5Stack, Powered by ESP32. The front side is embedded with a 540*960 @4.7" resolution e-ink screen which supports 16-level gray scale. The display is a GT911 capacitive touch screen, which supports multi-Point touch and a variety of gesture controls. Compared to a regular LCD, E-ink displays are easier on the eyes, which makes them a great choice for reading or viewing for longer period. Other benefits are the low power consumption, and the ability to retain the image even if power to the display is terminated. Integrated into the M5Paper are a multi-function button for operation, SHT30 temperature and moisture sensor, physical button for reset, and a TF-card (microSD) port for data storage.

Additionally, the FM24C02 internal eeprom chip provided 2K-bit (256x8)-EEPROM, which can be used to store vital data even when the device is off. A 1150mAh lithium polymer battery keeps the device going for long period, and battery life can be further preserved by using the RTC(BM8563) to set the device into a deep sleep mode, and wake it up again when needed. Three HY2.0-4P expansion ports are included which allow for building complex projects using the existing sensors in the M5Stack ecosystem.

Warning:
1. Do not expose to ultraviolet rays for a long time, otherwise, it may cause irreversible damage to the ink screen.
2. The low-power power management solution adopted by M5Paper is different from M5CORE and M5StickC devices. When using it, the PWR button is used as the power-on button (long press for 2s). If you need to shut down the device, you need to use the software API, or realized by pressing the reset button on the back. When using the USB power supply, it cannot be shut down.
3. If the program cannot be flashed normally (the prompt is over time or Failed to write to target RAM), you can try to reinstall the device driver. For driver downloading, please see the content at the bottom of the documentation.
