SKU:K049
Paper is a touch-enabled e-ink screen main control device launched by M5Stack, with the controller using ESP32-D0WDQ6-V3. The front of the device is embedded with a 540 x 960 @4.7" e-ink screen, supporting 16-level grayscale display. Paired with a GT911 capacitive touch panel, it supports two-point touch and various gesture operations. Compared to ordinary LCD screens, e-ink screens provide users with a better text reading experience and feature low power consumption and image retention when powered off.
The device integrates a dial switch, SHT30 temperature and humidity sensor, and physical buttons. For data storage, it reserves a TF-card (microSD) interface and integrates an FM24C02 storage chip, providing 2K-bit (256x8) EEPROM for user data storage during power loss.
It has a built-in 1150mAh lithium battery, and with the internal RTC (BM8563), it can achieve 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, bringing unlimited possibilities for subsequent application development.
