ardunaut and TheKitty contributed a nice Trinket pinout diagram to the Adafruit Forums!
Ardunaut: “A simple tool to deal with the wiring and programming. Suggestions will be appreciated. … and thanks for this tiny board , l’m having a great time recreating many of my projects with it.”
TheKitty: “I tweaked the diagram a bit. [Above.] The input is 5.5-16V, pin 4 cannot use regular analogWrite, and some other embellishments like those used by Pighxxx and GreyNomad in other Arduino diagrams. People have also asked what resistors are connected to what pins as they may give different impedances or pullup conditions. [Below] is a diagram that is a subset of the schematics showing the resistances. Hopefully I’ll have accompanying info on pullup/pulldown. I thought there was a post on pullup/pulldown/internal pullups earlier by a user but I cannot find it….”
