An E-Ink display module, 4.2inch, 400x300 resolution, with embedded controller, communicating via SPI interface, supports red, black, and white three-color display.
With advantages like ultra low power consumption, wide viewing angle, clear display without electricity, it is an ideal choice for applications such as shelf label, industrial instrument, and so on.
No backlight is required, and the display content of the last screen can be maintained for a long time after disconnecting the power supply; the power consumption is very low, basically only power consumption during refresh
SPI control interface, which can be connected to main control boards such as Raspberry Pi/Jetson Nano/STM32; on-board level conversion chip, compatible with 3.3V and 5V microcontroller interfaces
