【2.9-inch E-Paper display】128*296 resolution, using ESP32-S3 as the main control, excellent performance.
【Pure reflection mode】By reflecting ambient light instead of the backlight to display content, it is clearly readable in direct sunlight.
【Retain data during power outages】The data will not be lost even when there is no power.
【Outstanding readability】Wide viewing angle, high contrast and high reflectivity, not affected by light, providing a better reading experience
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.
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.
Customization can be discussed for bulk orders.
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.
