Description

This CrowPanel ESP32 1.54” electronic paper (E-Paper)HMI display uses 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 has a high resolution of 152*152, providing a vivid display effect, and uses a classic black and white display, suitable for various application scenarios. The built-in ESP32-S3 chip is used as the main control, ensuring robust performance and providing 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 features 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.

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.

1.54 inch E-Paper HMI display

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.
