The knob servo control module is a plug-and-play, easy to use servo controller with knob adjustment, return function, serial control three servo control modes.
Onboard mature and stable 8-bit MCU, used to generate high-resolution PWM signals, precise control.
Support manual mode and return mode, switch by button, with mode indicator.
Support knob adjustment or serial control in manual mode; when serial port is controlled, the matching host computer can be used or the external MCU can be connected.
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 , the 2 servos can be controlled separately.
Servo gear control accuracy: 0.09 degrees (the minimum PWM change value is 1us)
Support the servo gear with a control period of 20ms and a pulse width of 0.5-2.5ms.
Can directly use the 2S lithium battery charging head to debug and return to the servo gear.
Power supply voltage range: 5-9V
Board Size: approx. 29.8 x 47.2mm
