1.54-inch ePaper Module with SPI Interface for Raspberry, Arduino and STM32

The 1.54-inch ePaper module with SPI interface is an eInk display (ePaper/eInk) designed to provide clear and efficient display in electronic projects. This module is compatible with popular platforms such as Raspberry Pi, Arduino and STM32, making it easy to integrate into a wide range of developments.

This type of display stands out for its low power consumption, as it only requires power during image refresh. Once the graphic is loaded, the display keeps the image without the need for continuous power, making it an ideal option for devices that require low consumption and long battery life.

The technology used is microencapsulated electrophoretic display (MED), which uses small spheres with charged pigments suspended in transparent oil. These pigments move according to the electronic charge to form visible images that reflect ambient light, eliminating the need for a backlight. This allows excellent visibility even in direct sunlight, with a wide viewing angle of more than 170°.
