    Teensy 4.1 fuse location

    well that's not the problem, something is shorted and pulling the 5v down to about 2.5v and there is no 3.3v. I'm just going to order a new replacement.

    Out Pins defination

    On the 4.1 teensy there are pins labeled OUT1, OUT1D etc. What are these pin designated for and can they be used for digital pins or anything else?

    Teensy serial uarts voltage levels

    So the SPI levels will be different for 5v and 3.3v devices or is SPI at set predetermined voltage levels?

    Teensey 4.1 and ADS1118

    Joe You are correct but in the GIT there is a code change recommended by Christopher Mailer in the issue #12 to make a change in the Lib. Change the #if defined(__AVR__) to #if defined(__AVR__) || defined(CORE_TEENSY) and that should allow it to run on a teensy. Apparently this is not...

    Teensy serial uarts voltage levels

    Do 5v ttl serial signals have to be level shifted to 3.3v before connection to the teensy serial ports? I assume so but wanted to get confirmation. Thanks,

    Digital pin output current

    Through hole? Thanks...

    Digital pin output current

    I am seeing that the max output current of a digital pin on a 4.1 is 4mA. So to drive a typical TH red LED requires a transistor in order to get enough current?
