With the goal of creating a modern, more simplified 32bit Flight Controller, Flyduino made the KISS FC, which includes a completely new and proprietary firmware.
Flyduino's goal was to greatly simplify things, enabling pilots to spend more time flying and less time configuring. In most cases pilots simply choose their Airframe in the GUI and they are off (at least with KISS ESC), otherwise they can download presets of well known Pilots and of course can tweak the PID themselves using the GUI.
Much of the traditional set-up is already taken care of, allowing pilots to get into the air immediately after soldering the components in place.
The FC features integrated telemetry, which, in combination with their 32bit ESC line allows for live telemetry data via OSD on the FPV live feed, or in the KISS FC GUI
This provides useful informations like the battery voltage, current consumption, ESC temperature and motor RPM.
Other FC firmwares (eg. Cleanflight) can be ported for the use with the KISS FC.

Note - use care when plugging and unplugging a USB cable to this and any other device that has a surface mounted USB port - excessive force can cause unintended damage.
