      Hello dear friends.
      Can someone help me? I bought the USB Module connected to my M5stack fire.
      I see that there are some I/O pins on it but I have no Idea on how to refer to them on my Arduino code or on UIFlow.

      I there a code example where I can refer to?

      Thank you!!!

        I looked around for some examples for this too but so far have found none, here is the datasheet if it helps https://m5stack.oss-cn-shenzhen.aliyuncs.com/resource/docs/datasheet/module/MAX3421E_en.pdf
