I have an interest about Hobby CNC controllers.
I have some questions.
What is diffrencies between HOBBYCNC PRO Chopper Driver Board Kits and 4AUPC ?
Thanx for your interest.
With most stepper drivers, if you disconnect a motor wire while the unit is powered up, it will fry the driver chips, rendering the board useless. The Pro model has a built in protection circuit, whereas the 4AUPC does not, it is an older model.
The Pro board also runs a LOT quieter.
Spend the extra 20 bucks if you are looking at purchasing a board, and get the PRO.
