Waveshare 3inch E-Paper Display Module (G), 400×168, Red/Yellow/Black/White

E-Paper Module (G), 3-inch, 400 x 168, Black, White, Yellow, and Red. Microcapsule electrophoretic technology is used in e-paper displays. The idea is that when an electric field is applied, charged particles suspended in a clear fluid will migrate to the sides of the microcapsule. This allows the microcapsule to reflect ambient light and become visible, much like traditional printed paper.
An e-paper display with nearly a 180° viewing angle can clearly display text and images in natural or lamplight. It also doesn’t need a backlight. Because of the effect it has on paper, it is typically used as an e-reader.

Features:

1. No backlight keeps displaying last content for a long time even when power down
2. Ultra-low power consumption, basically power is only required for refreshing
3. SPI interface, for connecting with controller boards like Raspberry Pi/Jetson Nano/Arduino/STM32, etc.
4. Onboard voltage translator, compatible with 3.3V/5V MCUs
5. Comes with development resources and manual(driver board schematic, examples for Raspberry Pi/Arduino/STM32)
