Setting up Arduino IDE

Chances are, you picked up a Trinket because it is programmable with the Arduino IDE. The

Pro Trinket uses the same core chip as Arduino UNO, and the 5V Pro Trinket uses the same

clock rate and voltage so its pretty much a full Arduino-compatible, just smaller!

The only changes you may have to consider when adapting Arduino sketches are:

Pins #2 and #7 are not available

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 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.

The Fast Way

If you don't want to modify an existing Arduino IDE install, you can simply download our

ready-to-go and tested Flora/Gemma/Trinket-ified v1.05 right here:

Even though Trinket has a USB connector, it does not have a "Serial Console"

capability, so you cannot use Serial to send and receive data to/from a computer with a

seperate FTDI Cable!
