Description
Adafruit Pro Trinket – 5V 16MHz
Pro Trinket combines everything you love about Trinket with the familiarity of the common core Arduino chip, the ATmega328. It’s like an Arduino Pro Mini with more pins and a USB as well. The Pro Trinket has been designed with 18 GPIO, 2 extra analog inputs, 28K of flash, and 2K of RAM.
Like the original Trinket, it has onboard USB bootloading support using a MicroUSB. As well, an Optiboot support has been added, so you can either program your Pro Trinket over USB or with a FTDI cable.
The Pro Trinket 5V uses the Atmega328P chip, which is the same core chip in the Arduino UNO/Duemilanove/Mini/etc. What this means is that not only is Pro Trinket programmable using the Arduino IDE as you already set up, but 99% of Arduino projects will work out of the box!
