A 1.54\” ePaper display module from Waveshare, with a 200×200 resolution, 170 viewing angles and partial refresh support – controlled via SPI. ePaper displays are designed to replicate the appearance of ink on paper. Unlike regular displays, which lose their image when power is removed, ePaper screens are able to hold text and images indefinitely, even without power. ePaper screens are therefore ultra low power, designed to have a wide viewing angle and additionally have limited reflection under sunlight. The applications are limitless! These ePaper display modules from Waveshare come complete with an embedded controller PCB, communicating via SPI interface, and support partial refresh. This module includes a 1.54\” (200×200) eInk display & cable assembly designed to plug into your microcontroller\’s SPI interface. 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 SPI interface, for connecting with controller boards like Raspberry Pi/Arduino/Nucleo, etc. Comes with development resources and manual (examples for Raspberry Pi/Arduino/STM32) Specifications Operating voltage: 3.3V Interface: 3-wire SPI, 4-wire SPI Outline dimension: 48mm x 33mm Display size: 27.6mm x 27.6mm Dot pitch: 0.138 x 0.138 Resolution: 200 x 200 Display color: black, white Grey level: 2 Refresh power: 26.4mW(typ.)
