I want to use Arduino Nano board or teensy lc to communicate with teensy 4.1 wia tx rx pins. Teensy 4.1 is connected with audio board .
Can I connect Arduino Nano or Teensy lc to teensy 4.1 by (tx pin to rx pin , rx pin to tx pin ,gnd pin to gnd pin directly ) and read and write serial bytes ???? To play audio or Synth.
Like
Or any risk to connect pins???
