2.13inch E-Ink Display HAT for Raspberry Pi (Three-color)

Note: This 2.13-inch E-Ink display HAT is updated from V3 to V4 from 2023 onwards.

This is an E-Ink display HAT for Raspberry Pi, 2.13inch, 212x104 resolution, with an embedded controller, communicating via SPI interface, and supports red, black, and white three-color display. Due to advantages like ultra-low power consumption, wide viewing angle, and clear display without electricity, it is an ideal choice for applications such as shelf labels, industrial instruments, and so on.

Advantages of EINK

E-paper display utilizes microcapsule electrophoretic technology for displaying, the principle is: that charged particles suspended in clear fluid will move to the sides of the microcapsule when the 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 an e-reader due to its paper-like effect.

E-Ink (Electronic Ink) display has several benefits compared to other display technologies:

• High Visibility and Contrast
• Wide viewing angle
• Super low power consumption. It can retain the display for a very long time after power is removed

Standard Raspberry Pi 40 Pin GPIO Header
