That is a great idea.
I purchased 10 of these boards to do something similar.
eg: I plan on making these: IR remote control, Temperature, RTC, ultra sonic distance sensor and RFID.
Once made up, I will be able to just plug and play 
WARNING the PCB linked to here has a circuit error.
You Must corrected this error before you plug it onto an Arduino.
