    Max I/O current for 4.0

    I'm sure this has been stated somewhere, but I can't find what the maximum current draw can be on a 4.0 I/O pin

    That depends on the data rate (higher switching rates require more charging/discharging current for parasitic capacitances). Details are given in the iMXRT1062 data sheet which can be found together with all Teensy data sheets and reference manuals on the following page of the PJRC website: https://www.pjrc.com/teensy/datasheets.html
