* the specific APP or NFC reader is required for refreshing the e-paper screen.

Refreshing Example

Refreshed by ST25R3911B NFC Board

This product requires higher NFC power for refreshing due to its large size, therefore, it is better to use the ST25R3911B NFC Board solution. Recommended evaluation kit: 7.5inch NFC e-Paper Eval Kit. If a smart phone is used for refreshing, please make sure it has enough NFC output power, otherwise it may not be working.
