1.54 Inch Electronic Paper Screen for Raspberry Pie 4b

Without backlight, the display content of the last screen can be maintained for a long time after power failureThe power consumption is very low, basically only when the play is newE-ink screen can clearly display the picture under ambient light such as light and natural light, without backlight, and the visual angle is almost 180 degrees . Because it is comparable to the display effect of traditional paper, it is often used in applications such as readers.The application scenario is applicable to mall price labels, asset equipment labels, electronic shelf labels, conference brands, etcThe electronic ink screen uses the microcapsule electrophoretic display technology for image display. Its working principle is that the charged nanoparticles suspended in the liquid migrate under the action of electric field, and the display effect close to the traditional printing paper is formed by reflection under ambient light.Working voltage: 3.3VCommunication interface: 3 wire SPI, 4-wire SPIGray level: 2Dimensions: 37.32x31.8x1.05mmGlobal refresh: 8sDisplay size: 27.6x27.6mmRefresh power consumption: 264 mw (typ.)Dot pitch 0.138x0.138mmResolution: 200*200pixelsColour:WhiteMaterial:ABSPackage Contents:1 x 1.54 Inch Ink ScreenOnly the above package content, other products are not included.Note: Light shooting and different displays may cause the color of the item in the picture a little different from the real thing.
