So… yesterday my ardumoto shield went up in smoke.
I had measured the amps of the two cordless drill motors I am planning to use on my new robot. The meter said 1 amp per motor, but I believe that was not correct.
Anyway, my ardumoto went up in smoke. Now I am looking for more powerful drivers.
I came up with these 2 drivers:
The first one is a dual motor controller and the second one is a single motor controller.
Both motor specs say that their voltage range is 5.5VDC-36VDC. Is this logic voltage or motor voltage?
The pololu website sais: 5.5VDC-36V* "*Manufacturer specification. In our experience, shoot-through currents make PWM operation impractical above 16 V. "
However, the batteries will have a voltage of ~ 14-19V DC (18v batteries, ~18,6V when charged)
Second, it can be controlled by PWM. Would it be easy to modify the motor shield driver to make this work?
Thank you! ;D
