Description

This crisp, high-contrast black and white ePaper display is perfect for long-term displays with low power requirements. At 4.2 inches, it's perfect for a small sign - show daily specials, the weather forecast, product information, etc. Once the display is updated, all power connections can be removed and the graphic will remain on the display with zero power!
