Hi Ben

I'm not exactly sure what I'm doing wrong.
It worked with the ESP32-wroom. With the ESP32-S3,
I can't get it to work. I've already tried three different boards.
I also noticed that the green LED is flashing.
That happened with the SparkFun board, too.

Hello,

I wonder if the LED is interfering with the signal e.g. adding capacitance and stopping the signal from running at full speed? Maybe worth removing it?

Aha I didn't know you were using my board ok I'll see if I can replicate the issue there for you and let you know. It's slightly different to the Matrix version and so there could be something minor that's causing it.
