【3.7-inch E-Paper display】240*416 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.
【Ultra-low power consumption】It only consumes power when refreshing, extending battery life.
This CrowPanel ESP32 3.7” E-paper HMI Display has a resolution of 240*416 and a classic black and white dual-color presentation, bringing a reading experience like paper. It has high contrast and reflectivity, and thanks to hard-coated anti-glare technology, ensures excellent visual performance under various lighting conditions. The built-in ESP32-S3 chip as the main control ensures powerful performance and fast and stable 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 switch, allowing developers to easily program and control. The white acrylic case 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 display works in pure reflection mode, providing a comfortable reading experience close to paper. It is suitable for application scenarios such as shelf labels, price tags, badges, smart labels, and smart homes and is also an ideal choice for e-readers, smart wearable devices, and other portable devices.
Customization can be discussed for bulk orders.
