2.13 inch Passive NFC e-Paper Board
This development board integrates a 2.13 inch electrophoretic display that draws both power and data wirelessly through NFC. No battery or wiring is required, and an Android application is supplied for immediate content updates. The panel shows black and white pixels at 250×122 resolution within a compact ABS enclosure.
Makers prototyping battery-free displays
Engineers building NFC-driven signage, sensor read-outs or access badges will appreciate the zero-maintenance power model. Projects needing colour, greyscale beyond two levels, or continuous animation should consider alternative display technologies.
250×122 resolution refreshes in two seconds
The 250×122 pixel array updates in approximately two seconds once the NFC transaction completes, making it suitable for static or infrequently changing information. Faster refresh requirements would need a different panel.

Bu ürünle ilgili sorular
Does the 2.13" e-Paper generate heat or noise when refreshed repeatedly through NFC?
The passive NFC-powered display has no battery or active electronics that produce heat or noise; it only draws wireless energy during the brief two-second refresh, then remains completely inert.
What phone or reader must I already own to update the 250×122 display?
You need an Android smartphone with built-in NFC or an ST25R3911B NFC board; the supplied Android app handles the wireless powering and data transfer when the device is held close.
Can I keep using my older ST25R3911B NFC board to drive this 2.13" panel?
Yes, the board is explicitly listed as a supported refresh source, so it will wirelessly power and update the 250×122 e-Paper exactly as a smartphone does.
