Could you give me some advice on how to carry out a project that involves:
1 - one entry in 230VAC
2 - which powers a 230VAC/12VCD converter (IRM) in 12VDC for a fan (off board) and
3 -which also powers a 230VAC / 5VDC (IRM) converter for an arduino board and its modules and 2 230V relays driven by Arduino to power 2 lamps (off board).
Should I make 1 single card or 2 or 3?
I have the impression that the easiest way is to make a single map paying attention to distances (creepage and clearance).
What do you think?
