Spark fun Pro Micro #8

Sparkfun's ProMicro comes in 2 variations. A 3.3v and a 5v. Which should I be using?

Hi!

The pre-built firmware supports 5v/16MHz pro micros. If you order the 3.3v/8MHz you just need to change the rules.mk file to update the CPU frequency and rebuild the firmware.

So, they're all supported but I suggest you to use the 5V version. :)
