That is an E-Ink show HAT for Raspberry Pi, 2.13inch, 212×104 decision, with an embedded controller, speaking through SPI interface, helps the pink, black, and white three-colour show.
There isn’t a backlight so it could actually hold displaying the final content material for a very long time even when the facility is down. As these shows haven’t any backlight panels and it doesn’t want a steady energy provide to show the (static information with periodic intervals) information on the display screen, it has a terrific benefit of ultra-low energy consumption. Additionally, it has a large viewing angle, nice viewing impact below daylight, principally, energy to the show is just required for refreshing. For connecting with controller boards like Raspberry Pi/Arduino/Nucleo, and so on. SPI interface can be utilized.2.13 Inch 3 color show E-Paper Hat (B) is an E-Ink show HAT for Raspberry Pi 2.13 inch, 212×104 decision, with embedded controller and speaking through SPI interface. This show helps pink, black, and white three-colour show.
As a result of advantages like ultra-low energy consumption, vast viewing angle, the great impact below daylight, it is an ideal selection for purposes like shelf label, industrial instrument, and so forth. Options No backlight, retains displaying final content material for an prolonged time even when energy down Extremely-low energy consumption, principally energy is merely required for refreshing Suitable with Raspberry Pi 2B/3B/Zero/Zero W Preserved solder pads for SPI interface, for connecting with different controller boards like Arduino/Nucleo, and so on. Comes with growth assets and guide examples for Raspberry/Arduino/STM32) Specs Working voltage: 3.3V Interface: SPI Define dimension: 65mm? 30.2mm Show dimension: 23.71mm? 48.55mm Dot pitch: 0.194 ? 0.194 Decision: 250 ? 122 Show color: black, white Gray degree: 2 Refresh energy: 26.5mV(typ.)
