The front is embedded with a 1.54" E-Ink display with a resolution of 200x200, supporting black/white display. Compared to ordinary LCD screens, the E-Ink display provides a better text reading experience, with features such as low power consumption and image retention when powered off. For human-machine interaction, it offers a rotary switch and physical buttons, integrated LED indicator, and buzzer. It has a built-in 390mAh lithium battery, combined with an internal RTC (BM8563) to achieve timed sleep and wake-up functions, providing excellent battery life. There are independent power and reset (RST) buttons on the left side and bottom of the device, making it easy to use and debug. It offers a variety of peripheral interfaces (HY2.0-4P, M5-Bus, HAT module interface) to expand various sensor devices, providing infinite possibilities for subsequent application development.

It is recommended to refresh at intervals of (15s/refresh). Do not expose to ultraviolet light for a long time, as this may cause irreversible damage to the E-Ink display. CoreInk uses a low-power power management scheme different from CORE and StickC devices. When using, the PWR button is used as the power-on button (long press for 2s). To shut down the device, you need to use the software API or press the reset button on the back. Learn and Documents → DOCUMENTS Show more
