    Hello,

    The pin 3 in the trimming potentiometer U$5 (100K) is’t left floating?

    I’m using this model.

    Best regards

    No, that pin is connected to the ground plane of the board. That’s not obvious from the board diagram, but it is in the schematic.

    Hi,

    Thanks very much for the reply, I has it floating.

    I followed the eagle schematic

    I am trying to implement a similar circuit in a prototype for a flight controller, eliminating the function that it thinks it will not need, but I left the trims and a double pole switch for the purpose of testing.

    My circuit I already made the change and I connected pin 3 to GND. The reference is RV1

    Best regards
