## Can I chain panels or use with larger panels?
|

|

Yes you can. If you want to use with a 64x64 pixel panel you MUST configure a valid *E_PIN* to your ESP32 and connect it to the E pin of the HUB75 panel!
|

Yes you can. If you want to use with a 64x64 pixel panel (typically a HUB75*E* panel) you MUST configure a valid *E_PIN* to your ESP32 and connect it to the E pin of the HUB75 panel! Hence the 'E' in 'HUB75E'
|
||||
|
||||
This library has only been tested with a 64 pixel (wide) and 32 (high) RGB panel. Theoretically, if you want to chain two of these horizontally to make a 128x32 panel you can do so with the cable and then set the MATRIX_WIDTH to '128'.
