Servo control module is a plug and play, easy to use servo controller. Provides three servo control modes: Potentiometer adjustment, center return function. Can be used to test servo motor.
Connection method
Users can input voltage from green terminal or white XH2.54mm female socket.
Users can control servo motor by PC or MCU If it is not needed, it only needs to be connected to the power supply and motor.
If the servo is controlled by PC or MCU, it needs to be connected to PC or MCU. We can provide a software for PC. However, users need to write code on their own.
Step 1: Connect the input power supply to the input terminal;
Step 2: Servo motor 2 *3Pin connect to black male pins;
VCC: Connected to positive pole on servo motor;
GND: Connected to negative pole on servo motor;
S: Connected to input signal on servo motor connects.

Manual Control
Select Manual Control by 'S' button when LED indicator D1 turns ON and D2 is OFF;
Select Manual Control, Button Control and UART Control Contains. The default is Button Control. Automatic switching between two control modes. In other words, select the button mode while checking the rotation of the potentiometer. Select the UART mode when the UART receives a valid signal.
5.1>Button Control:
Rotate the potentiometer directly, the servo motor will change angle with rotation.
Rotation angle range 0~180°.
If connected to two servo motors, the two servo motors will perform the same action.
5.2>.UART Control:
Can receive UART command signal from PC soft or MCU.Baud rate 9600 and compatible 3.3 V/5V is the TTL level signal. It can control 2 servo motors separately.
Command format and description:
5.2.1>.#:Start symbol, indispensable;
5.2.2>. :Servo motor number. Range is 00 or 01;
5.2.3>.P: Constant symbol, indispensable;
5.2.4>.
5.2.5>.!: Constant symbol, indispensable;
For example:
Send #00P1500! It means servo motor M0 rotates to position at 90°.
Send #01P1000! It means that the servo motor M1 rotates to its position at 45°.
Users cannot also send commands, they can only operate in the control software.
Return to center function
Select Return to Center Control with the 'S' button when the LED indicator D2 turns ON and D1 is OFF.
When this mode is selected, the servo motor M0 and M1 will return to the center.
