RE: Frying 4-1 unit

A motor will draw a LOT more current when it is stopped and not allowed to rotate or even slowed down a lot.

The 4 in 1 has drive circuits for the motors that are rated at a certain current.

If you exceed this current rating for any length of time, the semiconductors will be damaged.

This will render it useless.

Hope this helps

Karl
