4.2" ePaper Display Module - Red/Yellow/Black/White (400x300)
Shopping information
This 4.2″ e-Paper module is a quad-colour display (Red/Yellow/Black/White) with no backlight and keeps the last displayed image for long periods even when powered off. Power is only needed during refreshes, so you’re barely using any power. The display also has a wide 170 viewing angle for visibility from most angles.
The SPI interface lets it connect to other controller boards like Raspberry Pi and Arduino, while a built-in voltage translator provides compatibility with both 3.3V and 5V MCUs. Included are online development resources and a manual, which makes it easy to get started!
