Hello, sorry for my English....

Please, can you give me the max frequency of pyboard can i provide on the pin out ?
I am looking for if the microPython on Pyboard can give me a possibility to generate a 3micro secondes frame. Is it possible to controle this rate of python, or inline asm ?

Very thank you for you answer.

best regards.

I don't know what the max frequency is.

You'll be able to get much shorter pulses using say a hardware timer than by using software.

You can definitely get less than 3 usec pulse. See this discussion: http://forum.micropython.org/viewtopic.php?f=2&t=829
