The built-in STM32 is used to generate high-resolution PWM signals with precise control. Support manual mode and return mode, switch by button, with mode indicator. Support control adjustment knob in manual mode. Number of Control Channels: 8 Channels. Control system: 0.09 degrees control accuracy (this means that the minimum PWM change value is 1us). Features: Supports servos with 20ms control period and 0.5-2.5ms pulse width (e.g. Futaba, Huisheng, etc.). You can directly use the 2S lithium battery charging head to debug and return to the control system. Power supply voltage range: 5-9V (in particular, the actual servo power supply voltage shall prevail). Each interface control chip has its own fuse recovery to prevent the control system from burning out by excessive current. Type: Control Circuit Control Board Material: PC+Metal Color: Blue+Black Size: 100x55mm Package Contents: 1 x Debug BoardOnly the above package content, other products are not included. Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing. The measurement error is +/- 1-3cm.
