Waveshare 7.5 inch NFC-Powered e-Paper Kit No Battery

Waveshare 7.5 inch NFC-Powered e-Paper Kit No Battery is a 7.5 inch passive NFC-powered e-paper evaluation kit designed for wireless image refresh without battery wiring. The kit combines the 7.5 inch NFC-powered e-paper display with the ST25R3911B NFC Board, so you can refresh the display through a compatible smartphone or use the included NFC reader solution for more reliable updating.

It uses NFC for both wireless power and data transfer, so the display can keep its image after refresh without needing a battery or continuous wired power.

How it works
To refresh the display, bring a compatible NFC-enabled smartphone or the included ST25R3911B NFC Board close to the e-paper. The display receives both wireless power and wireless data through NFC during the update process.

Why the kit matters
Because a 7.5 inch NFC-powered e-paper needs stronger NFC output than smaller tags, the included ST25R3911B NFC Board gives a more reliable refresh workflow for testing and deployment.

Phone compatibility note
The mobile workflow supports many iPhone and Android devices, but Samsung and Google phones are not supported in the tested compatibility list for this NFC refresh solution.
