== Notes and version constraints ==<br />
* The source lists different controller names; the exact hardware revision must be confirmed before use.<br />
* According to the FAQ, programming requires a JLink programmer, not an ST-Link V2.<br />
* Image file resolution must match the target display resolution.<br />
* Do not move the device during image refresh because the NFC communication distance is limited.<br />
* If a refresh fails, remove the reader and reposition it for another attempt.<br />
