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 degree viewing angle. It is usually used as e-reader due to its paper-like effect.
Onboard SPI Control Interface
For Use With Controller Boards Like Raspberry Pi/STM32/Arduino
| VCC | Power (3.3V / 5V input) |
|---|---|
