WaveShare 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 permanently visible without consuming energy until it is updated. The display presents content in three colors: black, white, and red, offering exciting design possibilities. With a high resolution of 400x300 pixels, text, symbols, and graphics are displayed sharply. This model is particularly suitable for battery-operated applications, as it requires almost no power in standby mode. Communication with the microcontroller is done via an SPI interface, which is supported by many common boards like Raspberry Pi, Arduino, or STM32. An integrated memory function ensures that the last displayed image is retained. The form factor is compact and lightweight, making it easy to integrate the display into enclosures or front panels. Due to its low power consumption, it is ideal for mobile use or smart DIY projects. The display remains excellently readable even in bright ambient light. The surface is anti-glare, which reduces reflections and makes the display easy to read. The control is particularly beginner-friendly thanks to provided sample codes.
