The knob steering gear control module is a plug-and-play, simple and easy-to-use steering gear controller. It has three steering gear control modes: knob adjustment, return function, and serial port command control. It is switched through buttons and has a mode indicator light.

The 2S lithium battery charging head can be directly used to debug and return to the steering gear. The power supply voltage range is 5-9V (the actual power supply voltage of the steering gear shall prevail). Control accuracy of steering gear: 0.09 degree (I .e. PWM minimum change value of 1us ), supporting steering gear with control period of 20ms and pulse width of 0.5-2.5ms. Number of control channels: 2 (MO and M1 steering gears), 2 steering gears are controlled at the same time when knob adjustment and return function are used, and 2 steering gears can be controlled respectively when serial port command is used. In manual mode, knob adjustment or serial port command control is supported; when serial port command control, a matching upper computer or an external MCU can be used. The on-board mature and stable 8-bit MCU is used to generate high-resolution PWM signals with precise control.
