2.9 Inch E-Paper Module Printed Circuit Board 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.
There is no backlight so it can keeps displaying last content for a long time even when power down. One highlighted feature of this module is ultra low power consumption. Basically power is only required for refreshing.For connecting with controller boards like Raspberry Pi/Arduino/Nucleo, etc.. SPI interface can be used.
