Hi,

is the max. baud rate 2Mbit/s oder can you go higher with these picos? I switched from my ESP8266 and I did not change this value, but I am wondering if I should...

I am using the 2040 with level shift :-)

Mayby you could add that information in the readme.md as well :-)

Hi Unlike the classic physical UART, Pico uses a virtual CDC controller that handles the speed itself. And there is a note in the read.me about that. Do a benchmark test and compare the result with my results obtained with a similar number of LEDs. If they are similar, you don't need to do anything. For me it always reaches maximum speed on the default settings.

Ups, you are so absolutly right. I don't know why I missed that. Thx!
