Dual Channel L298N PWM Speed DC Motor Driver Board - Red
Features: 1.Dual H-bridge motor driver£¬ can drive two DC motors or a 4-wire two-phase stepper motors 2.Built-in TSD£¬ without worrying about motor stall 3.Ultra-small size£¬ suitable for assembly and car Specification: 1.Module supply voltage: 2V~10V 2.Signal input voltage: 1.8-7V 3.Single working current: 1.5A 4.Peak current up to 2.5A 5.Low standby current (less than 0.1uA) 6.Built-in common conduction circuit£¬ the input terminal vacant£¬ the motor does not malfunction 7.Mounting hole diameter: 2 mm Description: motor drive module is ideal for use in battery-powered smart car£¬ toy cars£¬ robots. Supply voltage 2V ~ 10V£¬ can drive two DC motors or a 4-wire 2-phase stepper motors £¬can achieve forward rotation or reverse rotation£¬ it is possible to adjust the rotation speed. Each can provide continuous current of 1.5A£¬ peak current up to 2.5A£¬ thermal protection and can be automatically restored. Product Highlights: 1. Use of imported original chip£¬ built-in low on-resistance MOS switch£¬ minimal heat£¬ no heat sink£¬ small size£¬ low power consumption£¬ is ideal for battery powered. (L298N internal transistor switch£¬ low efficiency£¬ high fever£¬ need to add heat sink£¬ bulky£¬ L298N very easy to burn) 2. Dual 1.5A * 2£¬ the peak current to be 2.5A£¬ built-in thermal protection circuit£¬ do not be afraid motor stall burned£¬ automatic recovery after the temperature dropped. 3. Small size£¬ light weight£¬ 0 standby current£¬ is the ideal choice for your car model. [Attach function diagram] INx connected to the MCU I / O port£¬ MOTOR-A and MOTOR-B is connected to the motor. DC motor drive logic truth table: Product parameters: 1. Dual H-bridge motor driver£¬ can drive two DC motors or a 4-wire two-phase stepper motor; 2. The module supply voltage 2V-10V; 3. Signal input voltage 1.8-7V; 4. Single Operating current 1.5A£¬ peak current up to 2.5A£¬ low standby current (less than 0.1uA); 5. Built-in common conduction circuit£¬ when the input pin is left floating£¬ the motor does not malfunction; 6. Built-in thermal protection circuit with hysteresis effects (TSD)£¬ without worrying about motor stall; 7. Product Size: 24.7 * 21 * 5mm (length£¬ width£¬ height)£¬ ultra-small size; 8. The mounting hole diameter: 2 mm. 9. Weight: 5g Precautions: 1. Power positive and negative reversed will certainly cause damage to the circuit. 2. Output is shorted to ground or output short circuit£¬ and the motor stall£¬ the chip will heat protection£¬ but in the near or exceeding 10V voltage and peak current is greater than 2.5A situation can also cause chip burned.
