2.13inch passive NFC powered e-Ink / e-Paper display

This NFC-powered 2.13-inch e-paper display is battery-free and has a resolution of 250 × 122 pixels. You can easily transfer the images and data you want to display to the e-Paper via smartphone or NFC writer. The Android app is somewhat difficult to use because the menu navigation is in Chinese. However, sending a text or displaying an image is very simple. Alternatively, you can also use the Waveshare ST25R3911B NFC Development Kit NFC writer.
