Raspberry Pi board is NOT included. This is a color epaper display module designed to work with a Raspberry Pi and is intended for static signage rather than continuous video updates. Key benefits and requirements Color epaper display provides readable content with very low power consumption when displaying static information. Suitable for static displays such as tags, product labels, or signage where content changes infrequently. The color epaper update process is slower than active video displays, so be prepared for longer refresh times and plan updates accordingly. Do not keep the screen powered on for long periods without updating. If the display is not being refreshed, put it into sleep mode or power it off to avoid a voltage operating state that can damage the panel and is not repairable. The product is not intended for continuous timekeeping or clock displays. Frequent updates at short intervals can damage the epaper and are not repairable. Refresh intervals should be 180 seconds or longer for reliable operation. Usage guidance Before , you can review the English manual (including sample code) to learn more about this product. 23 practical use scenarios Retail tags and product labels that benefit from a clear, readable display without continuous power consumption. Static signage in stores, museums, or galleries for descriptions, hours, directions, or exhibit information that does not require frequent updates. Cafe or restaurant menus or daily specials where content changes infrequently and readability is important. Notes on compatibility and care This module requires a Raspberry Pi board (not included) for operation. Use the device as a static display with careful power management to prevent damage from prolonged voltage states. Do not rely on it as a clock or for frequent time updates. Follow the recommended refresh cadence to preserve longevity.
