What is it?

This CrowPanel ESP32 5.79” electronic paper HMI Display (E-Paper) is an advanced display technology. It uses an active matrix electrophoretic display and a hard-coated anti-glare display surface to keep the content visible even in sunlight, perfectly mimicking the appearance and reading experience of traditional paper.

It boasts a high resolution of 272*792, offering a vivid display effect, and features the classic black and white display, suitable for various application scenarios. Equipped with the ESP32-S3 chip as the main controller, it ensures robust performance and provides fast, stable data transmission through the SPI interface. The design includes multiple interfaces and buttons, such as the BAT interface, UART0 interface, 2x10 pin GPIO interface, back button, home button, and rotary switch, facilitating user development and operation. The white acrylic shell is not only beautiful but also protects the screen.

Based on the ESP32 chip, another highlight is its wide compatibility. It is compatible with three development environments: Arduino IDE, ESP IDF, and MicroPython, simplifying the secondary development process. Also, its ultra-wide viewing angle design allows you to enjoy the same brilliant image from any angle. The ultra-low power consumption feature consumes only a small amount of power when refreshing, ensuring long-lasting battery life. Pure reflection mode means no backlight is required, and information remains clearly visible after power failure, without worrying about information loss.

Why did you make it?

Due to its excellent characteristics such as low power consumption, high contrast, and high reflectivity, this electronic paper screen is widely applicable to shelf tags, price tags, badges, smart tags, smart home devices, e-readers, smart wearable devices, and other portable devices, making it an ideal choice for various smart devices and applications.

What makes it special?

• 5.79-inch E-Paper display, 272*792 resolution, black and white, using SPI interface communication;
