400x300 4.2inch 4-Farben E-Ink Display

With this 4.2-inch E-Ink display, you can take your projects to the next level - energy-efficient, high-contrast, and versatile. Thanks to e-paper technology, the image remains visible without consuming energy until it is updated. The display presents content in three colors: black, white, and red, providing you with exciting design possibilities. With a high resolution of 400x300 pixels, texts, symbols, and graphics are rendered sharply. This model is particularly suitable for battery-powered applications as it requires almost no power in standby mode. Communication with the microcontroller is via an SPI interface, which is supported by many common boards such as Raspberry Pi, Arduino, or STM32. An integrated memory function ensures that the last displayed image is retained. The design is compact and lightweight, making it easy to integrate into enclosures or front panels. Due to the low power consumption, it is ideal for mobile use or smart DIY projects. Even in strong ambient light, the display remains excellently readable. The surface is anti-reflective, reducing reflections and making the display easy to read. The control is particularly beginner-friendly thanks to provided sample codes.
