I got Teensy 4.0 today. Problem is I need this information if possible:
  • What is Vin to power the board from a battery?
  • What is the max digital I/O voltage?
  • What is the ADC resolution and max input voltage?

I read on NXP RT1060 datasheet that Vin through USB could be up to 5.5V, Digital I/O could be up to 3.6V, ADC input range is up to 3.6V and it is 12-Bit.

Your help is appreciated. Thanks
