there are two posts in the list today which both exemplify the same problem
LED Display
show that the poster did not read that some displays do not have the EL chopper as part of the package and just saw a lower price and
RS 485 Power supply .
show that the poster did not read the definition of "absolute maximum".

I will gladly give advise on a technical problem, but is it coming to the point where the discussion in this forum is about how to read?
