What is it?

This CrowPanel ESP32 2.13” electronic paper HMI Display (E-Paper) is an advanced display technology. It is equipped with 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 122*250, providing a vivid display effect, and uses 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 standout feature is its broad 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?

This electronic ink screen is not only an ideal choice for application scenarios such as shelf labels, price tags, badges, smart labels, and smart home devices, but also an excellent addition to electronic readers, smart wearable devices, and other portable devices.

What makes it special?

• 2.13-inch E-Paper display, 122*250 resolution, black and white, using SPI interface communication;
• ESP32-S3 as the main chip, frequency up to 240MHz;
• Support full viewing angle, clearly visible from any angle;
• High contrast and high reflectivity, can provide better visual performance;
• Pure reflection mode, no backlight required, completely relying on light reflection to display content, and the displayed content will not be lost even if the power is off;
• Hard-coated anti-glare display surface, it can keep the content clearly visible even under direct sunlight;
• Support Arduino IDE, ESP IDF, and MicroPython development environment to get a smooth development experience；
• Ultra-low power consumption and partial refresh function, significantly saving energy;
• Rich buttons and interfaces (such as GPIO interface, UART interface, home button, etc.) for easy development and operation.

Where to use Electronic label: supermarket or shelf product information and price； E-book reader； Electronic business card: display the corresponding participant information； Smart home and other applications.

Advantages of E-paper

Electronic paper displays can clearly display images/text under lighting or natural light, without backlight, with lower power consumption and longer life due to partial refresh. Because its effect is similar to that of paper, it is often used as an e-reader.
