 ### Driver Board and Flashing
 
-The e-ink screen used in this project is driven by the [Waveshare E-Paper ESP32 Driver Board](https://www.waveshare.com/wiki/E-Paper_ESP32_Driver_Board). The board was flashed with the sample `Loader_esp32wf` project provided by Waveshare, which exposes the web interface that this Python script interacts with.
