4.4 The PPM / I2C Breakout Board

The PPM breakout board is a small interface which simplifies the connection of servo-patch-cables to the flat ribbon cable.

Note: This interface is only necessary in case of using PPM controls like DJI Wookong.It is NOT needed in case of using Mikrokopter Flight Control.

The connection between PPM breakout board and HERKULES III ESCs is done with a flat ribbon cable with pressed red Micromatch connectors. If the red connector does not fit correctly on the breakout board, cut the small “Nose” from the connector.

The length of the flat ribbon cables should as short as possible to reduce in-coupling of magnetic distortions to the control signals. The connection to the Flight Control should be done with short servo-patch cables. Please check the polarity of the cables! Black (GND) is close to the PCB (printed circuit board).

Please check the polarity of this cable according the picture above to ensure a correct wiring.
