For reading an analog signal, I see analogPins are not 5.0v tolerant, but what really is the limit? 3.3000000000 or could 3.5 volts be applied to a pin for ~100ms?

Thanks KurtE, I saw that page but was hoping to see it clearly stated. The image was clear but just need to be sure.

I believe the current capability of a digital pin is around 20 ma. If you are just trying to drive a mechanical gage (like a car speedometer), I'm guessing the Teensy will work from a current perspective. What voltage...

I've use Teensy to write a PWM signal to a transistor to vary fan speed. Have a look at analogWrite on a digital pin.

What MCU are you using? Can you run the examples that come with the ILI9488_t3 lib?

I can only speak to 2.8" displays, as I use them in just about every project + great libraries from general display, UI tools, fonts (custom as well), to graphing tools, and more. pretty darn fast (with the right...

Kudos to anyone that is able to get these things working. Mine sucks out most of the solder, but not enough to allow parts to be removed.
