DFRobot I/O Expansion shield v5, Pin usage
Account cancelled 2013-04-24 14:48:27 2777 Views1 Replies Hello, I'm looking to use 2 shields on my Arduino Uno, The above mentioned I/O shield and a Video overlay board. Both shields require pin D2 for use and I was wondering whether it would be possible to wire the I/O shield to use pin D4 instead for the RS485 send/receive command.
It looks easy to re-wire, what I want to know is whether there are any reasons this would not work.
It also seems simple enough to call pin d4 instead of D2 but my programming skills are pretty rusty so I thought I'd see if others had done something similar

Hi, Yes you can use D4 instead of D2 . But you should change the hardware like the attach image ;)
