Description: The knob servo control module is a plug-and-play, easy to use servo controller with knob adjustment, return function, serial command 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 command control in manual mode; when serial port command 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 command, 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 Specification: Board Size: approx. 29.8 x 47.2mm Board interface description: VCC, GND: power interface XH2.54mm carrier: backup power interface, can be connected to 2S lithium battery; 2X3P pin header: 2 channel servo interface TX, RX: UART serial port pins SWIM, NRST: Reserve the MCU program download port Package Includes: 1 Piece Servo Motor Serial Port Control Board
