I finally opened up my Mega Pro Mini 3.3V, long retired it turns out, for something. Luckily I had bought the necessary connectors at the same time, and I always have an FTDI breakout board handy. But things I needed to figure out;

You need to add Sparkfun to your "Additional Boards Manager URLs" in the Arduino IDE;
https://raw.githubusercontent.com/sparkfun/Arduino_Boards/master/IDE_Board_Manager/package_sparkfun_index.json

Then select your Board as "SparkFun Mega Pro", and Processor as "ATmega2560 (3.3V / 8 MHz)".

But also, that each of the pins in output mode only supply about 40ma. Not the 200ma these lamps require. *sigh* Back to LEDs!
