# Pterodactyl Default Configuration
## Changelog
* Nov 2017:
* Copied and adapted from the Ergodox EZ equivalent
* Notable differences:
- Don't try to have the columns that don't exist, naturally
- Removed RGB keys, since there are no RGB LEDs in the Dactyl (as designed, at least)
* May 2020:
* Copied and adapted from dactyl base
* Notable differences:
- Support for Bluetooth via default Adafruit Feather 32u4
- Assumes processor lives in left half of split, not right
