The invention relates to an intelligent controllable-pitch propeller pitch feedback board, which is characterized in that a central control module acquires a voltage value signal of a potentiometer and a calibration value voltage signal of a fine tuning mode potentiometer from a pitch signaling device and then outputs a control signal to a current output module through an SPI bus to control the current output module to output a corresponding current; and corresponding current signals are sent to a central control box of the controllable-pitch propeller control system through the communication module, so that fine tuning of feedback current output is realized, and controllable-pitch propeller feedback potentiometer voltage calibration, screw pitch real-time feedback normal use state and potentiometer calibration value fine tuning state are realized. According to the feedback board circuit, an analog circuit is replaced by a digital circuit, screw pitch feedback signal output is more stable, and the temperature interference resistance is high; and the three potentiometers are combined with the keys, so that a one-key setting function is realized, and the original parameter setting difficulty is greatly simplified.
