Instructions:
Refer to the following pictures: the left side is connected to the servo, divided into three groups of upper, middle and lower,
which can be connected to three servo; the right side is connected by a single pin, near the side is negative pole (see identifier number), connected to the battery negative pole, pay attention not to be reversed, if the power supply connection is reversed, the IC will be burned; neglect the pins corresponding to S identifier. Turn on the power supply, the blue light will be on at the same time, and then only the first on the left is on, it is the manual potentiometer test, press the button, the middle light is on, it is returning to the middle test; the third light is on, automatic test. The connection method of testing ESC is the same as that of the servo, but the input end should not be connected to the power supply. The test motor should be connected to the ESC first when testing motor, then it is just like testing ESC.
By turning the knob, you can test the servo, no need for remote controller and receiver anymore.
If connected to ESC (brush motor or brushless), it can get rid of the remote control equipment and adjust the speed manually. It can be used to test the ESC or motor performance.
It is just what you need, cheap and practical little thing.
No more tedious connections to remote controllers and receivers
It is equivalent to the function of a "manual receiver"
Simulate remote control output by manual knob
