Teensy 4.0 5V tolerant pins

[ram-abhay]

All signal pins on the Teensy 4.0 are not 5V tolerant, so how do i recieve the telemetry? Did you use a logic level shifter? Also, the esc expects a 5v signal?

From what i have seen the Signal coming from the ESC is 3.6V (https://github.com/jacqu/teensyshot/blob/master/docs/KISS_telemetry.pdf). I assume this will similar for comparable ESC's. I had no issues with a Teensy 4 in that regard. As for sending a signal. The 3.3V from the teensy are enough. (I tested it with a T-motor F55A Pro II ,4 in 1)
