Arduino Freetronics Dual Channel H-Bridge Motor Driver Shield
Arduino Freetronics Dual Channel H-Bridge Motor Driver Shield Description
2 channel H-bridge for driving either two DC motors or a 4-wire bipolar stepper motor.
Uses Allegro A4954 dual channel H-bridge driver IC, with minimum 8V max 40V 2A peak rating with PWM control of both H-bridges.
External power connection for motor power supply, which can be jumpered to the Arduino to power the Arduino from the shield or vice versa.
Prototyping area to add your own parts.
Selectable current limit per channel: 0.6A, 1.2A, 2A.
