I am reading the Adafruit Trinket tutorial here. It states that BAT+ is used for battery INPUT:
If you want to power the trinket from a battery or power adapter or solar panel or any other kind of power source, connect the + (positive) pin here!
So I'm slightly confused by the Adafruit LED skateboard tutorial, which uses this pin for power OUTPUT.
- How can you use the power input pin for output?
- Why don't the LEDs draw way too much amperage through the Trinket board?
