Datasheet

higher voltage

USB Po wer Output - You can also snag the 5V power from the USB jack in case you

need 500mA+ current from your computer or portable USB power pack.

Breadboard friendly pins - You can easily plug this into a little breadboard and

have plenty of space for working and plugging stuff in

GPIO pins - 18 GPIO pins + 2 analog-only pins, at 3 or 5V logic, check the next

section for a detailed pinout guide

3 or 5V output - an onboard regulator provides 3.3V or 5V output for powering

LEDs, sensors, small motors, etc.

Reset Button - an onboard reset button will launch the bootloader when pressed

and the Trinket is plugged into a computer. If it is not connected to a computer, it's

smart enough to go straight to the program.

External Reset Pin - we bring out the reset pin so you can reset or restart your

Trinket on the road. If the Trinket is in a box or otherwise hard to get to, you can wire

up a button to this pin for an external reset button.

Three mounting holes make it easy to attach with 2mm screws (M2 metric or #2

imperial) or even tiny zip-ties, string, etc.

On the bottom there's a spot for a 2-pin JST-PH connector (http://adafru.it/1769). this is

optional and can be soldered on by hand. It will let you use a lipoly or AAA battery

pack (http://adafru.it/727) or a JST cable (http://adafru.it/drM) for other power input. It's

connected to the GND and VBAT pins
