Hello,
I'm using the Ardumoto from SparkFun to control a stepper motor.
It have a L298 dual full-bridge driver and protection diodes on board.
Somehow I manage to break one transitor from the L298 full-bridge driver. The transistor that fails is marked in red.
I'm not sure what the cause is, I can think of 2 possibilities:
- 1.7A current DC operation
- Manual trying to move the rotor in the reverse direction of its movement
What is more likely the problem?
Thank you.
