Overview
This is a flexible E-Ink display HAT, 2.9inch, 296≠128 resolution, with embedded controller, communicating via SPI interface, supports partial refresh.
Compared with normal e-Paper panels, this flexible panel allows bending without being damaged.
Combined with the advantages like ultra low power consumption, wide viewing angle, clear display without electricity, it is an ideal choice for applications where curved surface display is required, such as industrial instruments, smart wearable-devices, and so on.
Features
Flexible e-Paper, the display section is bendable (DON’T bend the FPC section)
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
Standard Raspberry Pi 40PIN GPIO extension header, supports Raspberry Pi series boards, Jetson Nano
Preserved solder pads for SPI interface, for connecting with other controller boards like Arduino/Nucleo, etc.
