This is a tiny 1.02\” E-Ink display module with a 12880 resolution and embedded controller. The module communicates via an SPI interface (making it great for a number of different development boards such as the Raspberry Pi) and supports partial refresh. Due to the advantages like ultra-low power consumption, wide viewing angle and clear display without electricity, it is an ideal choice for low-power applications. Features No backlight – keeps displaying last content for a long time even when powered down Ultra-low power consumption, power is only required for refreshing SPI control interface – works with a number of boards such as Raspberry Pi/Arduino Onboard voltage translator, compatible with 3.3V/5V MCUs Comes with development resources and manual (examples for Raspberry Pi/Arduino) Resources Product Wiki and code examples Package Contents 1x 1.02inch e-Paper Module 1x 8-pin wire Specifications Operating voltage: 3.3V / 5V Interface: 3-wire SPI, 4-wire SPI Outline dimension: 42mm 27mm Display size: 21.76mm 14mm Dot pitch: 0.175 0.17 Resolution: 128 80 Display colour: black, white Grey scale: 2 Full refresh time: 2s Refresh power: 26.4mW(typ.)
