Specifications OPERATING VOLTAGE--3.3V/5V INTERFACE---3-wire SPI, 4-wire SPI OUTLINE DIMENSIONS---65 × 30.2mm DISPLAY SIZE---48.55 × 23.70mm DOT PITCH---0.1943 × 0.1942mm RESOLUTION---250 × 122 pixels DISPLAY COLOR---Red/Yellow/Black/White GREY SCALE---2 FULL REFRESH TIME---25s REFRESH POWER<10mW STANDBY CURRENT<0.01uA (almost none) VIEWING ANGLE>170° Advantages Of EINK E-paper display utilizes microcapsule electrophoretic technology for displaying, the principle is: charged particles suspended in clear fluid will move to sides of microcapsule when electric field is applied, making the microcapsule become visible by reflecting ambient light, just as traditional printed paper. E-paper display will clearly display images/texts under lamplight or natural light, requires no backlight, and features nearly up to 180° viewing angle. It is usually used as e-reader due to its paper-like effect.
