M5Paper v1.1 Development Kit

M5Stack's M5Paper v1.1 is the updated version for M5Paper V1.0. M5paper is a core e-ink device with a touch-enabled display. Powered by the ESP32-D0WDQ6-V3, this device integrates a supersized 540 x 960 at 4.7" e-ink display which supports 16 grayscale levels.

The display is a GT911 capacitive touchscreen, which supports two-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 periods. 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 CoreInk are a multi-function button for operation, SHT30 temperature and moisture sensor, physical buttons, and a TF-card (microSD) port for data storage.

Additionally, the FM24C02 internal EEprom chip providing 2K-bit (256x8) EEPROM can be used to store vital data even when the device is off. A 1,150 mAh lipo battery keeps the device going for long periods and battery life can be further preserved by using the RTC (BM8563) to set the device into a deep sleep 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: do not expose to ultraviolet rays for a long time, otherwise it may cause irreversible damage to the e-ink screen. The low-power power management solution adopted by M5Paper is different from that of CORE and StickC devices. When in use, the PWR button is used as a power-on button (long press 2 seconds). If the device needs to be shut down, use the software API or press the reset button on the back. When using a USB power supply, it cannot be shut down.
