 Please use an [alternative library](https://github.com/2dom/PxMatrix) if you bought one of these.
 
+## Other hardware notes
+There appers to be an issue with some ESP32-S3 based products when using this library. The thinking is the high-frequency DMA output generated by this library affects the S3's sensitive WiFi radio if the PCB isn't designed to minimise EMF. 
+* 'Adafruit MatrixPortal S3' in particular does not work well with this library. Do not buy if you want to use with this library and WiFi. [Discussion](https://github.com/mrcodetastic/ESP32-HUB75-MatrixPanel-DMA/discussions/258#discussioncomment-12274566)
