Version Option
Features at a glance
- No backlight, keeps displaying last content for a long time even when power down
- Ultra-low power consumption, basically power is only required for refreshing
- It comes with online development resources and manual (examples for Raspberry Pi/Jetson Nano/Arduino/STM32/ESP32).
Optional for e-Paper driver board - Standard Raspberry Pi 40PIN GPIO extension header, supports Raspberry Pi and Jetson Nano series boards
- Adopts Raspberry Pi HAT+ standard to improve interoperability, helping the users to design and develop faster, easy to use with other peripherals and extend more functions for Raspberry Pi
- Adapting SPI interface for connecting with controller boards like Raspberry Pi/Arduino/STM32/ESP32, etc.
- Onboard voltage translator, compatible with 3.3V / 5V MCUs

the principle is: charged particles suspended in clear fluid will move to sides of microcapsule
when electric field is applied, making the microcapsule become visible by reflecting ambient light.
just as traditional printed paper E-paper display will clearly display images/texts under lamplight
or natural light, requires no backlight, and features nearly up to 180° viewing angle.
It is usually used as e-reader due to its paper-like effect.
Optional for e-Paper driver board
