Description

Paper v1.1 is a touch-enabled e-ink screen main control device launched by M5Stack, featuring the ESP32-D0WDQ6-V3 controller. The front is embedded with a 540 x 960 @4.7″ e-ink screen that supports 16-level grayscale display. It is paired with a GT911 capacitive touch panel, supporting two-point touch and various gesture operations. Compared to ordinary LCD screens, the e-ink screen provides users with a superior text reading experience, along with low power consumption and image retention when powered off.

This development board integrates a rotary switch, an SHT30 temperature and humidity sensor, and physical buttons. For data storage, it includes a TF-card (microSD) interface and an FM24C02 storage chip, offering 2K-bit (256×8) EEPROM for user data storage during power loss.

It comes with a built-in 1150mAh lithium battery, combined with an internal RTC (BM8563) to enable sleep and wake functions, providing strong battery life. Additionally, it offers 3 HY2.0-4P peripheral interfaces, allowing for the expansion of various sensor devices, opening up endless possibilities for future application development.

Note 1. Do not expose the e-ink screen to ultraviolet light for extended periods, as it may cause irreversible damage.
2. The low-power management solution used in M5Paper differs from that of CORE and StickC devices. When in use, the PWR button (press the rotary switch) serves as the power button (long press for 2s). To power off the device, use the software API or press the reset button on the back. When powered via USB, the device cannot be turned off.
3. If you encounter issues with downloading programs (e.g., timeout or “Failed to write to target RAM”), try reinstalling the device drivers. For driver downloads, please refer to the content below the documentation.
