Guided Tour

Let me take you on a tour of your Trinket M0! Each Trinket M0 is assembled here at Adafruit and comes chock-full of

good design to make it a joy to use.

Micro B USB connector - We went with the tried and true micro-B USB connector for power and/or USB

communication (bootloader, serial, HID, etc). Use with any computer with a standard data/sync cable.

RGB DotStar LED - Instead of an always-on green LED we provide a full RGB LED. You can set it to any color in

the rainbow. It will also help you know when the bootloader is running (it will turn green) or if it failed to initialize

USB when connected to a computer (it will turn red). By default after you boot up the Trinket M0 it will turn a

lovely violet color.

Red #13 LED - this LED does double duty. Its connected with a series resistor to the digital #13 GPIO pin. It pulses

nicely when the Trinket is in bootloader mode, and its also handy for when you want an indicator LED.

ON LED - this LED lets you know when the Trinket is powered up, it will shine green whenever the 3.3V regulator

is working.

10 Header Pins - Check the next page for the pinout details but these have all the power and analog/digital IO

you need! Solder 0.1" headers or wires directly

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.
