Product details

CoreInk is a brand new E-Ink display from the M5Stack Cores series, controlled by the ESP32-PICO-D4. This new device features a 200x200 1.54-inch black-and-white E-Ink display. Compared to a conventional LCD, E-Ink displays are gentler on the eyes, making them an excellent choice for extended reading or viewing. Additional advantages include low power consumption and the ability to retain the image even when powered off.

To control the device, CoreInk integrates a multifunction button, a physical button, a built-in status LED, and a buzzer. The device also includes a 390mAh LiPo battery and an RTC (BM8563) for precise timekeeping and deep sleep functionality. CoreInk offers independent reset and power buttons, as well as expansion ports (HY2.0-4P, M-BUS, HAT expansion) for connecting external sensors to enhance functionality, providing unlimited possibilities.
