We’ve put together a simple setup script which will get you set up in a jiffy, just: git clone If you’re running Raspbian you can just grab the contents of our GitHub repository. You’ve got two choices when it comes to setting up the software. We recommend our Jumper Jerky to make all the necessary connections. If you have male to male wires and an extra breadboard handy you can use the Adafruit Pi T-Cobbler to clarify where the SPI, power and Serial pins are.

A Raspberry Pi ( model A or B will do ) running Raspbian.

6 female to male jump wires for power/programming.To get your Trinket and Pi connected, you’re going to need a few bits and bobs. The 3 remaining pins are reserved for power, ground and reset. Two of these can be configured as analog inputs and two as PWM outputs. The skills you pick up from tinkering with a Trinket and learning how to program it will also be transferable should you decide to try any Arduino products. One that you can not only use with your Pi, but as a stand-alone controller. The trinket is a cheap and flexible alternative to a PWM driver, or an analog to digital converter. Generate precisely timed signals, like the one needed for WS2812 LEDs.Read cheap analog sensors, such as temperature or light intensity.Generate PWM ( Pulse-width-modulation ) signals, for Servos/Variable LED brightness.The Trinket can do many things that your Pi either can't do, or isn't great at:

The Trinket and the Pi are a very complementary pair.

Warning: Make sure you use the 3.3v Trinket, don't connect a 5v one directly to your Pi! Why Combine A Trinket And A Pi? Programming the Adafruit Trinket from your Raspberry Pi
