On a 5V Trinket, the GPIO are 5V output level, and can be used with 3V inputs but may damage electronic devices that are 3V input only!

On a 3V Trinket, the GPIO are 3.3V output level, and should not be used with 5V inputs. Don't connect a motor or other high-power component directly to the pins! Instead, use a transistor to power the DC motor on/off

Next we will cover the 5 GPIO (General Purpose Input Ouput) pins! For reference you may want to also check out the datasheet-reference above for the core ATtiny85 pinĪll the GPIO pins can be used as digital inputs, digital outputs, for LEDs, buttons and switches etc.
