What customers say
This Adafruit eInk display earns high praise for its exceptional clarity and extremely low power needs, perfect for battery projects. A key advantage noted by users is the integrated SRAM, which greatly simplifies memory management, especially for microcontrollers with limited RAM. Users consistently appreciate the crisp, readable quality of the panel. Furthermore, the excellent documentation and user-friendly libraries significantly lower the learning curve for eInk technology. While the slow refresh rate is expected for this display type, the component offers substantial value due to its integrated features and reliable support ecosystem. Users advise careful handling of the ribbon cable connection during setup.
Know before you buy
No. One of the primary benefits of this eInk display is its ability to retain a static image even after power is completely removed, making it ideal for low-power projects.
Yes, the module is designed to be logic-level safe for both 3V and 5V systems, offering broad compatibility with most common microcontroller platforms.
The integrated SRAM acts as a frame buffer. It allows your microcontroller to store the image data locally on the display module, which reduces the memory load on your main processor.
Yes, it features a matte, anti-glare surface and high-contrast eInk technology, which provides excellent readability in bright daylight conditions.
No, this specific model does not include a touchscreen or an integrated frontlight. It is a standard monochrome eInk panel designed for static content display.
The display uses an 18-pin EYESPI standard FPC connector with a flip-top mechanism. This allows for a secure, solder-free connection when paired with compatible breakout boards or cables.
