This is a three-colour (red, black and white) 1.54" ePaper 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)
