I have got a number of emails regarding PCB details. So here are the details.

In my new prototype (using a SMPS), I am supplying a seperate supply for 12 v operation. This works even better upto 49 volts.

mmmmm.

I just knew why you commenting on my topic, You also do the same on other users topics, so this is normal.

It looks we Have anothe (EVA) on the forum

But belive me one (EVA) is just fine.
