Hello, i currently have a nixie tube clock Arduino project on the run and the V1 turned out alright there were a few bugs which i plan to iron out on Rev 2. As well as fixing a lot of version 1's problems i would like to add a new piece of functionality and if there were room i would just stick a wifi shield in there but thats just not possible right now as i have compacted the regular Arduino Uno into a much smaller space and it is all SMT now. I would like to do the sane with the wifi shield so that the bare bones Arduino inside is able to connect to a predefined website and get some alarm data among other things so i can update the clock alarms via my phone/computer.
So my question is how can i change the current wifi shield so that it is smaller more compact and does not have anything that is needed on it. I know it does not need the JTAG or MACB headers as i will be using ICSP header to program the main chip. What else can i remove from the schematic that i would not be using?
