Specification:
This motor driver are using MX1508 ic to drive two channel motor.
It's similar with L298N, can drive 2 motor with both CW & CCW direction,
and control speed by PWM.

• 2 channel mini motor driver
• Voltage Input : 2-10VDC
• Rated Current: 1.5A
• Peak Current: 2.5A (less than 10second)
• Direction and PWM control
• Dimension: 24.7 x 21 x 5mm
• Weight: 5g

Connection:
+ = Battery Input Positive(2-10V)
- = Battery Input Ground 
MotorA = Motor A 2 wire
MotorB = Motor B 2 wire
IN1 & IN2 = Motor A signal 
( IN1 = High + IN2 = LOW (Motor Clockwise), IN1 = LOW + IN2 = HIGH (Motor Anti Clockwise), IN1 = High + IN2 = HIGH (Motor Stop) )
IN3 & IN4 = Motor B signal 
( IN3 = High + IN4 = LOW (Motor Clockwise), IN3 = LOW + IN4 = HIGH (Motor Anti Clockwise), IN3 = High + IN4 = HIGH (Motor Stop) )
