- 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
- Provide complete supporting information manual (example program for Raspberry Pi/Jetson Nano/STM32)
