Since the beep trim or other electromagnetic elements can influence the control signals of the Hall sensors, I now use shielded cables for long connections between sensor and board.
There is usually a printed cover on the Cyclic base that secures the connector.
This can be closed again with 2 cable ties.
The cable assignment for 2 axes is that the shielding and the yellow-green cable are connected to the black or brown sensor cables.
At the PICK-UP these come to the place marked with GND.
+ 5V is always in the middle of the 3 or 3x2 plugs for the connections for the PICK-UP boards.
The black signal lines on the shielded cable come into the side marked SGN (closer to the USB port)
The 2nd picture shows the assignment on axis 5 for Collective and 7/8 for Cyclic
