2.9-inch E-Paper E-Ink Display Module (B) – 296×128, Red / Black / White, SPI
The 2.9-inch e-Paper Module (B) – features low power consumption, a wide viewing angle, and a paper-like display that doesn't require power to maintain the image. Ideal for price tags, shelf labels, industrial indicators, and many other applications.
Key Features:
- No backlight, retains displayed content for a long time even when powered down
- Ultra-low power consumption, power is mainly needed for screen refreshing
- SPI interface, enabling cooperation with development boards such as Raspberry Pi, Jetson Nano, Arduino, STM32, etc.
- Built-in voltage translator, compatible with microcontrollers operating at 3.3V / 5V
- Supplied with complete development resources and manual (examples for Raspberry Pi/Jetson Nano/Arduino/STM32)
Advantages of E-Ink Technology
E-Paper displays utilize electrophoretic microcapsule technology. The principle of operation is that charged particles suspended in a clear fluid move to the sides of the microcapsule under the influence of an applied electric field. This makes the microcapsule visible by reflecting ambient light, similar to traditional printed paper. An e-Paper display clearly presents images and text in lamplight or natural light, requires no backlight, and offers a viewing angle of nearly 180°. Due to its paper-like effect, it is often used in e-readers.
Built-in SPI Control Interface
Allows for easy connection to popular control boards.
