Description
This 7.5-inch e-paper E-Ink display HAT for Raspberry Pi with SPI interface provides low power consumption, wide viewing angle and a paper-like display of 3 colors (red, black, white) without electricity.
Advantages Of E-Ink
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.
Features
- No backlight, keeps displaying last content for a long time even when power down
- Ultra low power consumption, basically power is only required for refreshing
- Standard Raspberry Pi 40-pin GPIO extension header, supports Raspberry Pi series boards, Jetson Nano
- SPI interface, for connecting with controller boards like Raspberry Pi/Jetson Nano/Arduino/STM32, etc.
- Onboard voltage translator, compatible with 3.3/5 V MCUs
- Comes with development resources and manual (examples for Raspberry Pi/Jetson Nano/Arduino/STM32)
