Stepper Motor Driver MX1919 2.5A Controller Board Dual Channel H-Bridge Brushed DC Motor Low power consumption PWM For Smart Car Robot 

2.5A power-enhanced motor drive module with silicone wire, pin header, terminal. The power supply voltage is 2V~10V, which can drive two DC motors or one 4-wire 2-phase stepping motor at the same time. It can realize the function of forward and reverse and speed regulation, with thermal protection and automatic recovery.

• 1. Two-way H-bridge motor drive, can drive two DC motors or one 4-wire two-phase stepper motor at the same time
• 2. Module supply voltage 2V-10V
• 3. Signal input voltage is 1.8-7V
• 4. Single working current 2.5A, low standby current (less than 0.1uA)
• 5. Built-in anti-common state conduction circuit, when the input terminal is suspended, the motor will not malfunction
• 6. Built-in overheat protection circuit (TSD) with hysteresis effect, no need to worry about motor stall
• 7. Product size: 31 x 32 x 5mm (length, width and height), small size, suitable for assembly and vehicle
• 8. Mounting hole diameter: 2 mm.
• 9. Weight: 11g

Precautions:

• 1. The inverted positive and negative power will cause damage to the circuit.
• 2 The output is cut to ground or short-circuit output, and the motor position, the chip protects the heat, but at the voltage close to or greater than 10 V and the maximum current is greater than 2.5A the situation can also cause burned chip

• T here may be 0- 2 Cm error due to M Annual measurement Thank you for your understanding!
