Dual-way Knob Servo Serial Control Board MG995 SG90 Debug Board Module Servo

Description: Dual-way Knob Servo Serial Control Board MG995 SG90 Debug Board Module Servo IntroductionThe knob servo control module is a plug-and-play, simple and easy-to-use servo controller. It has three servo control modes: knob adjustment, centering function, and serial command control. Parameter1. The on-board mature and stable 8-bit MCU is used to generate high-resolution PWM signals with precise control;2. Support manual mode and return to center mode, switch by button, with mode indicator light;3. Support knob adjustment or serial command control in manual mode;4. When controlling by serial port command, you can use the matching host computer or connect to an external MCU;5. Number of control channels: 2 channels (M0 and M1 servos), the two servos can be controlled at the same time when using the knob to adjust and the centering function, and the two servos can be controlled separately when using the serial port command;6. Servo control accuracy: 0.09 degrees (that is, the minimum change value of PWM is 1us)7. Support steering gears with a control cycle of 20ms and a pulse width of 0.5-2.5ms (such as Futaba, Huisheng, etc.)8. You can directly use the 2S lithium battery charging head to debug and return to the steering gear9. Power supply voltage range: 5-9V (specifically based on the actual power supply voltage of the steering gear used)10. Product size: 49.2* 29.8mm11. Product weight: 11g Instructions for use1. About wiringConnect VCC and GND to the power supply, and insert the servo into the 2X3P pin header, where VCC is the positive pole, GND is the negative pole, and S is the signal terminal.2. Manual modeThe manual mode is selected by the on-board button, and the manual light is on and the neutral light is off. Manual mode includes knob control and serial port control. The default is knob control. The system will automatically switch between the two control modes, that is, the knob control is selected when the potentiometer is turned, and the serial port control is selected when the serial port receives a valid control command.2.1 Knob control: directly turn the potentiometer to control the steering gear to rotate within the range of 0-180°2.2 Serial control: The onboard MCU can receive and parse the servo position commands (baud rate 9600, compatible with 3.3V/5V level) sent from the host computer, external MCU and other equipment, so as to control 2 servos respectively, among which the rudder The format of the machine position command is: #P!, each meaning is as follows:a, # is the starting symbol, indispensable;b, means the number of servos to be controlled, 2 in total (range: 00-01 corresponds to the servos M0 and M1 respectively);c, P is a fixed symbol in the instruction format, which is indispensable;d, represents the width of the PWM signal (range: 0500-2500 corresponds to 0-180° respectively);e,! is the end symbol of the instruction, which means the end of an instruction and is indispensable.For example: send #00P1500! to turn the servo M0 to 90° Send #01P1000! to turn the servo M1 to the 45° positionTake the upper computer LCSC as an example. First, prepare a USB to a TTL serial port module (such as CH340, FT232, etc.). The TX, RX, and GND of the serial port module are respectively connected to the RX, TX, and GND of the control board. Choose the correct port number. After the connection is successful, drag the No. 0 and No. 1 progress bars to control the M0 and M1 servos respectively, as shown in the figure below:3. Back to center modeSelect the return to center mode through the on-board button. At this time, the manual light is off, the center light is on, and the servos M0 and M1 will be at the center at the same time. Tips:Because the steering gear is a relatively power-consuming device (such as MG995/MG996 steering gear), the power supply current for the steering gear needs to be sufficient. When the steering gear is rotating, if the on-board LED flickers, the steering gear is not controlled or error Obviously large abnormalities, it means that the power supply current is not enough and the power supply needs to be replaced.
