Digital Servo Tester / Controller
Product Parameters
1. High-precision potentiometer, which can control the servo in real-time.
2. On-board voltage display module, which can monitor the voltage of power supply equipment in real-time.
3. High-resolution PWM signal, on-board 8-bit MCU, can make the control accuracy higher.
4. Support manual servo controller/servo reset back to center, switch by reset buttons under servo control knob.
5. Servo controller accuracy: 0.09° (refers to the PWM limit small change value of 1us).
6. Two power supply equipment link interfaces. (5-8.4V)
7. On-board 2-channel PWM digital servo interface, which can be controlled by a high-precision potentiometer.
8. Size: 2*1.4inch / 50*35mm, Weight: 0.03 lb / 13.5g
How to use:
1) Supply power to the controller, the voltage can be 5~8.4V, the specific voltage is subject to the actual use of the servo’s rated voltage;
2) The servo is plugged into the 3Pin servo port.
3) The power-on default potentiometer control mode, the servo rotates synchronously when the knob is turned;
4) The button below the knob can switch the mode, press respectively to
“Manual Mode”: Knob control.
“Neutral Mode”: Return to the center position.
Information of Controller
- "+" Positive Pole
- "-" Negative Pole
- "S" Signal Terminal
- Manual Mode: Knob Control.
- Neutral Mode: Return to Center Position.
Voltage Real-time Monitoring
Through the voltage display module, the voltage of the power supply equipment can be monitored in real time to prevent the voltage from being too low to continue to control and test the steering gear.
Manually Control The Servo
Through the high-precision potentiometer, the angle synchronous rotation of the 2 steering gears can be controlled in real time.
Servo Return To Center
Through the reset button, the angle of the 2-way servo can be reset to 90°.
