H-Bridge Shield - Large Motor Control for Arduino

PWM Controlable H-Bridge
Arduino forward & backwards large motor control

An H-Bridge by definition its an electronic circuit which enables a voltage to be applied across a load in either direction. meaning that it can control devices like DC motors to spin in both directions. Using two pwm digital pins it creates an easy way to plug one large motor and control its speed and direction.

Features:
Selectable pwm outputs ( through two jumper cables you can control the h-bridge from any 2 pwm outputs)
Optocoupled circuit which isolates the motor power supply from the the arduino.
External power input ( 5 to 12v)
Stackable shield

would u think that Hbridge can handle a motor with traxxas motor? it needs at least 6 amps to move forward and backwards with load on it?????

Can you be more specific about the motor,

i would say that with proper heatsink and a fan blowing air through the shield it would handle it quite well, the transistors are able to deliver 8A max

Boas,

ainda vendes o kit? eu mandei mensagem atraves do blog mas não sei se ainda está activo e tenho alguma urgencia.

Cumprimentos
