DC 5-8.4V 6 Channel Rotary Knob Servo Driver Controller Board Servo Tester Overcurrent Protection for Arduino DIY Robot Arm Part

1. Using imported high-precision potentiometers, 6 energy machines can be controlled 1 to 1 with real-time synchronous 1:1 control.
2. There are over-current protections for the 3 channels of No. 0, No. 1, and No. 2 of the control board to prevent the steering gear from being burnt out due to excessive current.
3. There is a small button under each knob of the control panel. Press it once and the steering gear will be in the centered state, and the knob cannot control the rotation of the steering gear; press it again to release the centered state, and the knob can continue to control the rotation of the steering gear.
Wiring instructions:
+: Connect 5~8.4V power supply
-: Connect to the negative pole of the power supply
Generally speaking, the steering gear to be controlled needs a few V, just connect a few V to the control board.
