Hello all,

Is it possible to built a 256-Channel OR 512 Relay Control Serial Board ?
I am new in electronics .

Any one can help Please

Thanks All

 

Sure it is.

 

Could you please post any circuit do this ?

Thanks so much

 

I just agree it's possible. I don't have such a circuit handy but it's something a microcontroller can do.

You can buy them, there are a few suppliers.
