A small pin mapping reference to arduining with the Trinket (5V version).
I have to admit that this little one from Adafruit is awesome!
Happy Wiring !!!…
Note: to use PB4 as analog output (PWM) aditional software setting is needed.
The ATtiny85 microcontroller from Atmel is the “heart” of the Trinket.
Tip about soldering pin headers.
When you use the Trinket in a breadboard and press the reset button, the thin pcb (0.8mm) use to bend a little.
Remove the unused pins an keep the plastic for a better support.
Using this method you can press you reset button with confidence.
