MG995 SG90 Servos Knobs Control Module Dual Servo Serial Port Motor Drive Controller Board Steering Gear Debugging | Инструменты

 The knob servo control module is a plug-and-play, easy-to-use servo controller with knob adjustment, return function, serial command control, and three servo control modes.

• The onboard mature 8-bit MCU is used to generate high-resolution PWM signals with precise control.

• Support manual mode and return mode, switch by button, with mode indicator;

• Support knob adjustment or serial command control in manual mode;

• The serial port command control can use the matching host computer or connect to the external MCU;

• Number of control channels: 2 channels (M0 and M1 servos). When using the knob adjustment and return function, the 2 servos are controlled at the same time. When using the serial command, the 2 servos can be controlled separately.

• Steering gear control accuracy: 0.09 degrees (that is, PWM minimum change value of 1us)

• Support steering gear with a control period of 20ms and a pulse width of 0.5-2.5ms (such as Futaba, Huisheng, etc.)

• Can directly use 2S lithium battery charging head to debug and return to the steering gear

• Power supply voltage range: 5-9V (specifically based on the actual servo supply voltage)

Board interface description:

• VCC, GND: power interface;

• XH2.54mm carrier: backup power interface, can be connected to 2S lithium battery;

• 2X3P pin header: 2-way servo interface;

• TX, RX: UART serial port pins;

• SWIM, NRST: Reserve the MCU program download port.
