3.1-Inch 320x240 E-Ink E-Paper Display – Black and White
The 3.1-Inch E-Ink E-Paper Display is a high-contrast, ultra-low-power black and white e-paper screen designed for clear, sunlight-readable visual output in a wide range of embedded and portable applications. Featuring a 320x240 pixel resolution and a pixel density of 129.03 PPI, this display delivers crisp text and graphics with exceptional readability under various lighting conditions — ideal for IoT devices, handheld instruments, smart tags, and e-book readers.
Powered by the UC8253 driver IC and using a SPI interface, this display ensures easy integration with popular microcontrollers such as Raspberry Pi, Arduino, ESP32, and STM32. It supports horizontal and vertical display orientations, offering flexibility for both portrait and landscape layouts. With multiple refresh modes, including full refresh (3s), fast refresh (1s), and partial refresh (0.5s), the 3.1-inch e-paper module provides dynamic and efficient screen updates for different use cases — from static image rendering to fast data refresh in sensor dashboards or electronic signage. Operating on 3.3V and designed for 0–50 C environments, it’s perfectly suited for indoor and semi-outdoor projects.
