A compact ESP32-based dev kit with a built in E-ink/ePaper display (as well as Wi-Fi, Bluetooth and an onboard lipo battery).
Controlled by the ESP32-PICO-D4 this new device includes a 200x200 1.54" Black and White E-Ink Display. 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 low power consumption and the ability to retain the image even if power to the display is lost.
For control the CoreInk integrates an multi-function button, a physical button, integrated status LED and buzzer. The device also includes a 390mAh Lipo RTC (BM8563) for controlling accurate timing and deep sleep functionality. CoreInk features independent reset and power buttons, expansion ports (HY2.0-4P, M-BUS, HAT expansion) for attaching external sensors to expand functionality for unlimited possibilities。
Warning: Please avoid using high refresh rates, recommended refresh rate is 15s/per refresh. Do not expose to ultraviolet rays for a long time, otherwise it may cause irreversible damage to the ink screen.
