NFC-Powered e-Paper Display

This 2.13 inch display uses passive NFC technology to draw both power and data wirelessly. No battery is required, removing the need for charging or wiring. An Android app is supplied for quick content updates via smartphone or NFC reader. It suits projects that need occasional updates without a permanent power source.

ABS Case and Wide Viewing Angle

The module fits inside a protective ABS case that keeps it light and durable. The 250 by 122 pixel panel shows black and white content with two grey levels on a 49.70 by 21.75 mm active area. A dot pitch of 0.194 by 0.194 mm and a viewing angle greater than 170 degrees ensure clear readability from most positions.

Replacing Wired or Battery Modules

This display replaces e-paper screens that rely on batteries or wired connections for refresh cycles. The jump is worth it when installation space is tight, when maintenance access is limited, or when a completely cable-free surface is preferred. It is not suited for applications that need video-rate updates or colour output.
