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.\u003c\/p\u003e\n\u003cp\u003e\u003cimg alt=\"\" src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0056\/7689\/2250\/files\/1920x600-1_fa1eb120-4981-4d54-b60a-2cad93edca4b.webp?v=1765434835\u0026amp;width=700\"\u003e\u003c\/p\u003e\n\u003ch2 id=\"features\" data-id=\"Features\"\u003eFeatures\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eDeveloped based on ESP32, supports WiFi\u003c\/li\u003e\n\u003cli\u003eBuilt-in 4M Flash\u003c\/li\u003e\n\u003cli\u003eLow power consumption display panel\u003c\/li\u003e\n\u003cli\u003eNearly 180-degree viewing angle\u003c\/li\u003e\n\u003cli\u003eHuman-machine interaction interface\u003c\/li\u003e\n\u003cli\u003eMagnetic back design\u003c\/li\u003e\n\u003cli\u003eBuilt-in lithium battery\u003c\/li\u003e\n\u003cli\u003eRich expansion interfaces\u003c\/li\u003e\n\u003cli\u003eDevelopment Platform\n\u003cul\u003e\n\u003cli\u003eUiFlow1\u003c\/li\u003e\n\u003cli\u003eUiFlow2\u003c\/li\u003e\n\u003cli\u003eArduino IDE\u003c\/li\u003e\n\u003cli\u003eESP-IDF\u003c\/li\u003e\n\u003cli\u003ePlatformIO\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2 id=\"includes\" data-id=\"Includes\"\u003eIncludes\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e1 x CoreInk\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2 id=\"applications\" data-id=\"Applications\"\u003eApplications\u003c\/h2\u003e\n\u003cp\u003e\u003cimg alt=\"\" style=\"width: 80%;
