Question : What is the input voltage range for the module?
Answer : The module supports a supply voltage range of 2V to 10V.
Question : What is the maximum current rating for the module?
Answer : The module can provide a continuous current of 1.5A and a peak current of up to 2.5A.
Question : Does the module have built-in thermal protection?
Answer : Yes, the module has built-in thermal protection to prevent motor stall and automatic recovery after temperature drop.
Question : How do the two inputs work when using for single dc motor? Is one forward and one reverse?
Answer : In1 and In2 are for motor A. In3 and In4 are for motor b. Set In1 High and In2 low Motor A turns one direction, set In1 low and In2 high, motor A rotates opposite direction. PWM the high signal for speed control.
Question : What chip is on this board?
Answer : It's an MX1508. Chip is marked: MX1508 1739H
Question : Can the inputs be driven with 50hz pwm for speed control?
Answer : Yes, the inputs can be driven with 50Hz pwm signal for speed control.
Question : Can control input be a voltage or does it have to be pwm?
Answer : Both are OK. You don't need to connect to PWM if no speed control. 100% duty cycle PWM is actually voltage.
Question : Will this work on a pi zero?
Answer : Yes It will.
Question : Can this supply 3v to a motor and control polarity for forward and reverse?
Answer : It's an H-Bridge, so yes, it can reverse the polarity to reverse the motor. Voltage will be controlled by your voltage input, and you can PWM the inputs to effectively reduce the voltage to the motor.
Question : I can PWM control the motor for only just one direction? Why not the other way?
Answer : Set In1 High and In2 low, motor A turns one direction, Set In1 low and In2 high, motor A rotates opposite direction, PWM the high signal for speed control.
Question : Can you reverse polarity for motor reverse?
Answer : If input 'IN1' is high and 'IN2' is low the motor will go in one direction. If input 'IN1' is low and 'IN2' is high the motor will go in the opposite direction.
Question : Is there a 12V version of this that can handle 1.5A?
Answer : You can try our other one ASIN: B07L892P54, High working power to 46v.
