This servo tester is a highly useful tool to manually control and test servos and Brushless Motor ESCs. Just provide an input of 5V to the tester and connect your servo to one of the outputs. You can then manually control the servo rotatory angle by turning the onboard rotatory knob.
This servo tester has 3 built in modes, which can be toggled using the onboard switch -
Manual Mode: This mode can be used to control the servo with the onboard rotatory knob
Neutral Mode: This mode can be used to center the servo
Auto Mode: This is an automatic mode in which the tester sweeps the servo from one end to another
Can be used to control servos and Brushless ESCs
