Windows Driver Installation
To use a Trinket, Gemma, or Flora on Windows you will need to install a driver for your board.
Follow the steps below depending on the board you're using:
Adafruit Trinket/Gemma (black board) Driver Installation (http://adafru.it/eTU)
Arduino Gemma (teal board) Driver Installation (http://adafru.it/eTU)
Flora Driver Installation (http://adafru.it/eTU)
Note on Mac OSX or Linux you don't need to install any driver to use Adafruit's boards.
Only follow these steps if you're using Windows.
Adafruit Trinket/Gemma Driver Installation
If you're using an Adafruit Trinket or Adafruit Gemma (the black circuit board Gemma, not the
teal or blue/green Arduino Gemma--for Arduino Gemma skip below to the next
section (http://adafru.it/eTU)) follow the steps below to install a custom driver for the board.
First download the signed Windows 10, 8, 7, Vista, XP driver below and unzip its contents to a folder
on your computer:
Download Signed Adafruit
Trinket/Gemma Driver
http://adafru.it/djr
If for some reason you need it there is also an older unsigned driver for Windows 7, Vista,
XP (http://adafru.it/eFa). Stick with using the signed driver above unless you know you need the
unsigned driver.
Then plug in the Trinket or Gemma to a known-good USB cable to start the process. You should
see the green power LED lit and the red bootloading LED pulse indicating that the Trinket is ready
to start bootloading. If you've programmed the Trinket since getting it, you can always get it back to
the bootloader state by pressing the small onboard reset button.
Finally, follow the steps on this page to install the custom Trinket/Gemma
driver. (http://adafru.it/cDY)
Remember this driver is for the Adafruit Gemma board and not the Arduino Gemma board. If
your Gemma has a black circuit board use this driver, but if it has a teal or green/blue circuit
board skip down to the next section.
