Zener Diodes ...
#1
Hello me again...
I still have this question about the zener diodes spot on the pcb...
"cut connections for diodes use" you mean : cut the connections on the board ?
What is the use of these zener diodes ? To cut the "back" current from the motor or to cut over voltage from the power supply circuit ? Could that have save 2 of my miniEngine which burned ?
Why don't you say anything about it in your documentation ?
Another point : impossible to find any 12v-0,2A zener or shottky
only 12v-0,5W or 12v-1,3w which one should I choose ?
Thank you

I do recommend not using the zener diodes. After some more time and experience in electronics, these don't help and might actually just hinder proper functioning of the system.
