Where can I find a data sheet for the 4 Relay Shield? I downloaded the 'Eagle files", the .BRD and .SCH files I cannot open. I'm on Windows 10.
Thanks

I just purchased a package of components from Arduino including their 4 Relay Shield, Code A000110. The package did not include a datasheet for this board, and the online support information did not include one.
Just need help finding a data sheet if there is one. Thanks.
