110M high-speed optocoupler is used to isolate the input signal, effectively preventing the interference of the driver board to the control board, making the system more stable and reliable. 2Ideal for robot competitions, car competitions, etc. 3The basic components of the drive module body are patches, which has a high degree of integration 4Well-designed layout, beautiful and small size, onboard two high-power DC motor drives 5The large heat sink can effectively dissipate the drive module under high current and maintain the good stability of the module 6When driving the motor, the maximum rated current of the module can reach 60A, and the on-resistance is only 0.003 ohm 7High switching frequency, up to 60KHZ Item Type: DC Motor Driver ModuleThe control interface is very simple: when A1.A2 = 0.0 is the brake; when A1.A2 = 1.0 is the forward rotation; when A1.A2 = 0.1 is the reverse rotation; PA is the PWM input (motor speed adjustment); G is for the control board Common ground pin (channel B is controlled in the same way)Both 3.3V and 5V microcontrollers can control this module, and only need one motor power (12V ~ 30V) 1 x Module Please note that the new type and old type of this product will be sent randomly, and make sure you will not mind before ordering.
