296x128, 2.9inch E-Ink display module, SPI interface
Overview
This is an E-Ink display module, 2.9inch, 296x128 resolution, with embedded controller, communicating via SPI interface, supports partial refresh.
Due to the advantages like ultra low power consumption, wide viewing angle, great effect under sunlight, 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 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)
