Overview
This is an E-Ink display module, 1.54inch, 152x152 resolution, with embedded controller, communicating via SPI interface, supports yellow, black, and white three-color display.
Due to the advantages like ultra low power consumption, wide viewing angle, clear display without electricity, it is an ideal choice for applications such as shelf label, industrial instrument, and so on.

Features
No backlight, keeps displaying last content for a long time even when power downUltra low power consumption, basically power is only required for refreshing SPI interface, for connecting with controller boards like Raspberry Pi/Nucleo, etc.
Comes with development resources and manual (examples for Raspberry Pi/STM32)
