Good day
I found your work on the forum - DRO.
It is perfect and professionally done. A PCB with an integrated power supply is a very good idea.
I want to ask you if it is possible to buy PBC, or can I get documents for the production of PBC?
I have a small lathe of my own making, and a DRO would be useful.
I apologize for writing in English, but I do not speak Polish.
(I also speak German, Italian, Russian)

I look forward to receiving your reply.
Sincerely

Ing Salaj Jozef
