Specification Brand : Adafruit BulletPoint1 : Drive four solenoids, two DC motors bi-directionally, or one stepper motor BulletPoint2 : Built in kick-back diodes internally so you dont have to worry about the inductive kick damaging your project BulletPoint3 : PWM input per driver so you can control motor speed. BulletPoint4 : Two full H-bridges (four half H-bridges) BulletPoint5 : 5. Distribution of long-axis motor connection lines: (blue: A +, black: A-.
