Description
This is a three-colour (red, black and white) 1.54" E-Ink display module with a 200x200 resolution, embedded controller communicating via SPI interface.
Due to the advantages like ultra-low power consumption, wide viewing angle and clear display without electricity, it is an ideal choice for low-power projects.
Features
- No backlight - keeps displaying last content for a long time even when power down
- Ultra-low-power consumption - power is only required for refreshing
- SPI interface - for connecting with controller boards like Raspberry Pi/Nucleo etc.
- Onboard voltage translator, compatible with 3.3V/5V MCUs
- Comes with development resources and manual (examples for Raspberry Pi/Jetson Nano/STM32)
