My firmware is based on the original code from Rolf Bakke (KK2_1V6) and therefore have most of the features from his firmware intact. I have however added quite a few features of my own and some on request from others.

Key features:
  • Three flight modes: Acro, SL Mix and Normal SL.
  • Simplified ESC calibration (performed without transmitter).
  • Reduced servo jitter on M7 and M8.

  • Lost model alarm.
  • Lowest battery voltage logged and displayed on the LCD screen.
  • Quiet ESCs while browsing the KK2 menus.
  • Advanced channel mapping.
  • Flight timer.
  • OLED display support via (soft) I2C. Only available on KK2.1++ AiO R9 (for now).
  • Adjustable LCD contrast/OLED brightness.
  • ...and more. See the included Readme.txt and Whatsnew.txt files for more information.
