Datasheet

The Pro Trinket 5V uses the Atmega328P chip, which is the same core chip in the Arduino

UNO/Duemilanove/Mini/etc. at the same speed and voltage. So you'll be happy to hear 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!

Here's some things you may have to consider when adapting Arduino sketches:

Pins #2 and #7 are not available (they are exclusively for USB)

The onboard 5V regulator can provide 150mA output, not 800mA out

You cannot plug shields directly into the Pro Trinket

There is no Serial-to-USB chip onboard. This is to keep the Pro Trinket small and

inexpensive, you can use any FTDI cable to connect to the FTDI port for a Serial

connection. The USB connection is for uploading new code only.

The bootloader on the Pro Trinket use 4KB of FLASH so the maximum sketch size is

28,672 bytes. The bootloader does not affect RAM usage.

Trinket is not supported on Linux operating system at this time - try Mac OS or

Windows!
