Flight controller board is soldered at the top of a damper board, and has Inertial Measurement Unit and barometer soldered on it as well. The damper board reduces vibration the IMU and barometer receives, and provides sockets for Flat Film Wire cables which connects it to ESC boards and 3-in-1 board.
Flight Controller CPU runs Real-Time Operating System which acquires readings from all sensors and sends control signals to motors ESC units.
IMU precision is improved by using 2 chips, put on the board in different orientations. The board has cutouts around the IMU chips, which are also covered by silicon. This helps with accurately measuring acceleration by nullifying stress caused by mass of the board.
The known variants are listed below.
