The product is industrial-grade design, stable and reliable, with anti-static circuit, transient suppression protection, under-voltage protection, interface ESD and over-voltage protection, etc.;Support a wide range of voltage 9-36V, the maximum continuous load current is 12A (without heat dissipation), 15A (simple heat dissipation), 20A (thick large heat sink);Similar to L298 drive logic, it can control speed regulation, forward and reverse rotation and braking with three wires (PWM, IN1, IN2); Support full PWM, you can directly use the buttons to control the forward and reverse rotation, the effective range of PWM is 0.1%~100.0%;It can provide 5V power supply for microcontrollers and other controllers, and has 5V output overcurrent protection and access signal overvoltage protection.The power supply voltage is 6V-36V (the voltage is too low and the load current is too large to damage the module, so the circuit board is marked as 9-36V), the power supply must not be reversed or exceed 37V, otherwise the module may be burned out, it is recommended to use the power supply A 20A fuse is connected in series at the input end.The rated current of the driver is 12A without heat dissipation. The rated current of 12A~15A needs to be used for simple heat dissipation, and the rated current of 15A~20A needs to be used for thick heat dissipation. (Easy heat dissipation - such as placing a 1mm thermal silica pad under the module and then fixing the module to the device wall with a 5mm copper column)The control signal interface (orange) can provide 5V to the user, and the single-chip microcomputer does not need additional power supply, and the maximum power supply current is 0.5A.Control signal high level voltage: 3.0V~5.5V, compatible with 3.3V and 5V TTL level;Control signal low level voltage: 0V~0.8V, 0V when floating;When the control signal voltage is 5V, the control signal current is 50uA.PWM valid range: 0.1%~100.0%;PWM signal frequency range: 0~100KHz (20KHz recommended);PWM minimum effective pulse width: 200ns.Working temperature -25-80.Product size: 55x55x25mm (length, width and height).Mounting hole diameter: 3mm.Colour: redMaterial: PCBPackage Contents:1 * Motor Drive Board ModuleOnly the above package content, other products are not included.Note: Light shooting and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm.
