Hi.

I'm building a shield for an home automation shield and I want to include an RS485 module in it.
I found this shematic of a shield and copy the desing on my file.

org shield;

But in my file , eagle gave me an error the the max481CSA have no supply. I follow the same supply trough a resistor as the org file.

I show you my shematic on join piece.

On your schematic you don't have for the MAX481CSA, pin 5 (Gnd) connected to Gnd and you don't have pin 8 (Vcc) connected to Vcc.

Thank Paul.

I found weird that it wasn't connected in the shield design. I just found why; I have to use the "invoke"
function in eagle that I never use.

It was showing those pin.

Thanks again for your time.
