What is it?

This 2.9-inch ESP32 electronic paper (E-Paper)HMI display has a resolution of 128*296 and a classic black and white dual-color presentation, giving you the same reading experience as paper. It has high contrast and reflectivity, as well as hard-coated anti-glare technology. You can have an excellent visual experience in any lighting condition. The built-in ESP32-S3 chip is the main control, with powerful performance and fast data transmission through the SPI interface. It is also equipped with various interface and button designs, including BAT interface, UART0 interface, 2x10 pin GPIO interface, back button, home button and rotary switch, allowing developers to easily program and control. 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?

This E-Paper screen is widely used in shelf labels, price tags, badges, smart labels, smart home devices, e-readers, smart wearable devices and other portable devices. It is an ideal choice for various smart devices and applications.

What makes it special?

• 2.9-inch E-Paper display, 128*296 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.
