Suffering from the trouble of connecting the servo to the flight control of the traversing machine, and the single flight control does not have an ammeter, I simply drew a 20*20 flight control distribution board with an ammeter, which is suitable for the F722mini flight control of Aocoda and other manufacturers. In fact, it is also common, but you need to confirm the wiring sequence of the SH terminal yourself. The servo is powered by an independent 5V5A step-down module, with a current measurement range of 80A, a sampling resistor of 0.5mΩ, and a voltage dividing resistor of 820KΩ.
