M5Stack ESP32 Core Ink Development Kit

CoreInk represents a significant advancement within the M5Stack cores portfolio, providing an innovative E-ink display experience. Driven by the ESP32-PICO-D4 chip, this remarkable device features a 1.54-inch black and white E-ink display with a resolution of 200x200 pixels. In contrast to traditional liquid crystal displays (LCDs), E-ink displays are recognized for their eye-friendly characteristics, making them particularly suitable for prolonged reading or viewing activities. Furthermore, these displays exhibit minimal power consumption and possess the ability to retain the displayed image even in the absence of power.

Controlling the CoreInk device is straightforward, facilitated by its integrated multi-function button, physical button, status LED, and buzzer. These features deliver intuitive control and feedback, enhancing the overall user experience. The device is equipped with a 390mAh lithium polymer battery, providing adequate power for extended use. Additionally, it incorporates a Real-Time Clock (RTC) for precise timing control and supports deep sleep functionality to optimize energy conservation.

The CoreInk distinguishes itself with independent reset and power buttons, facilitating convenient operation. Additionally, it is equipped with expansion ports (HY2.0-4P, M-BUS, HAT expansion) that enable the connection of external sensors, thus expanding its functionality significantly. With CoreInk, users have the opportunity to unleash their creativity and explore a multitude of possibilities.

Caution:
Do not expose the device to ultraviolet rays for a long time, or it may damage the screen.

Precautions: It is advised to refrain from prolonged high-frequency refresh cycles during use. The recommended refresh interval is every 15 seconds. Additionally, exposure to ultraviolet rays should be minimized; sustained exposure may result in irreversible damage to the ink screen. The low-power management solution implemented by CoreInk differs from that employed by CORE and StickC devices. To activate the device, the PWR button should be pressed for a duration of two seconds. If it is necessary to power down the device, please utilize the software API or the reset button located on the back of the device.
