This Instructable will show you how to build your own FM radio receiver shield to be used with an Arduino board. The radio chip we are going to be using is the AR1010 on a breakoutboard found at Sparkfun or Electrokit and there will be code to get you up and running provided later on. We are going to use an laser cutter for the shield fabrication.
First we build up our circuit using eagle. There are many Instructables out there on how to do it such as this or this. You can download my eagle files I have been using when building this board below. Things to consider is that when you are going to be using the laser cutter for doing pcbs you have to remeber that it is one sided pcbs that is be far easiest and also that the traces has to be 15 mil or wider otherwise the laser and etching process might etch them away.
