Electronic Ink Display Module designed for clear, paperlike visuals and low power operation Key benefits Paperlike readability: Microcapsule electrophoretic technology produces contrast images that look like printed paper under ambient light, making content easy to read without a backlight. Always visible in normal lighting: Works well in indoor lighting and skylight conditions with a viewing angle close to 180 degrees, so information remains readable from wide angles. Lasts without power: The eink screen holds the last displayed image after power is removed, preserving information during outages. Energy efficient: The module consumes power mainly during screen updates, enabling longterm use with minimal active power draw. Easy system integration: SPI communication and standard logic voltage options simplify connection to microcontrollers and single board computers. How this solves common problems Eliminates the need for continuous backlighting, reducing power and maintenance costs for signage and shelf labels. Ensures critical information stays visible after power loss, useful for unattended installations. Provides a wide viewing angle so multiple viewers can see the display clearly from different positions. Key specifications Item type: Electronic Ink Display Module Material: electronic ink Working voltage: 3.3V or 5V. IO level voltage must match the supply voltage. Communication interface: SPI Resolution: 360 x 240 Pixel pitch: 0.2 mm x 0.2 mm Display colors: black and red Grayscale: 2 Update time: 16 seconds Power behavior: Low power design; power is mainly used during screen updates. The screen retains the last image without power. Compatibility and integration notes Use SPI interface for communication. Select 3.3V or 5V supply according to your host device. Ensure IO level voltage is consistent with the chosen supply to avoid damage. Suitable for microcontrollers and single board computers that support SPI and the listed voltage levels. Typical use scenarios Retail shelf labeling and tags: paper tags or LED displays with readable, lowpower electronic labels that retain and product info even during power interruptions. Warehouse inventory and logistics: Fixed signage on shelving and storage areas that is easy to read from multiple angles and updates only when data changes. Meeting room and queue displays: Lowpower signs for conference rooms, food counters, or unmanned stores where clear visibility and long retention are required. Package contents 1 x EInk Display Module This module is a practical choice when you need a readable, lowpower display that mimics printed paper, holds content without power, and integrates via SPI with common 3.3V or 5V systems.
