Features 1.The basic components of the drive module body placement, high integration, sophisticated board layout designed, beautiful and compact, single-board high-power DC motor drive module size of just 60 x 42mm. 2.When drive motor, the module maximum rated current up to 30A, and turns on only 0.0028ohm resistor. 3.High switching frequency, the most up to 60KHZ, which effectively prevent the startup of the motor bring unpleasant low frequency. 4.3.3V and 5V microcontrollers can control this module, and the only way the motor power supply (12V - 30V). 5.Built to meet standard specification, strictly follow factory quality control. Specification Condition: 100% Brand New Item Type: Motor Drive Module Material: Plastic Color: As picture shown The control interface is very simple: A1.A2 = 0.0 when brake; A1.A2 = 1.0 when forward; A1.A2 = 0.1 when reversing; PA PWM wave input (motor speed control); G for the control board common ground pin; 200mA at 5V control voltage output, Driver Module Mechanical Parameters: Length: Approx. 60mm/2.4in Width: Approx. 42mm/1.7in Height: Approx. 20mm/0.8in The distribution of four positioning holes 3mm/0.1in, each pitch of 52 x 34mm/2 x 1.3in Package List 1 x Motor Drive Module
