Keep the UNO's fancy USB connection with none of the size! The Pro Trinket is the Arduino Compatible solution for all of your small project needs.
Say hello to Adafruit's newest addition to the Trinket lineup, the Pro Trinket! Not only does is support the much loved ATmega328P, but also has a custom bootloader that gives you a handy USB interface.
The Trinket Pro has a total of 18 GPIO, 2 extra analog inputs, 28K of flash, and 2K of RAM. With all this capability packed into a form factor of only 1.5" x 0.7" x 0.2" (without headers), you will be surprised how easy it is to migrate your project from an Uno down to the tiny Pro Trinket.
Keep in mind that because of the Pro Trinkets USB bootloader, the flash storage (Arduino sketch size) is reduced to 28K instead of the Uno's 31.5K. This should only be a problem if your pushing the absolute limit of the Uno's flash memory when you got to make the switch over to the Pro Trinket.
The 3V Pro Trinket runs at 12MHz which differs from the 16MHz of the Pro Trinket 5V and Arduino Uno. While this shouldn't affect most libraries, it may have an impact on libraries which are timing critical. Make sure to read the documentation on the libraries you wish to use before selecting the Pro Trinket 3V.
