Waveshare 7.5 inch 800x480 Pixel Red Black White E-Paper E-Ink Display Module (B) for Raspberry Pi Pico, SPI Interface Features 1. No backlight, keeps displaying last content for a long time even when power down 2. Ultra low power consumption, basically power is only required for refreshing 3. SPI interface, requires minimal IO pins 4. 2x user buttons and 1x reset button for easy interacting 5. Comes with development resources and manual (Raspberry Pi Pico CC++ and MicroPython examples) Advantages Of EINK 1. 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. 2. E-paper display will clearly display imagestexts 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. Specification 1. Operating voltage: 3.3V 2. Display color: Red, black, white 3. Resolution: 800x480 pixels 4. Grey scale: 2 5.
