Arduino FM radio receiver shield

by mwasp

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.

Step 1: Eagle 1

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.

Step 2: Eagle 2 Layout

Once you have your layout done it is time  to export it to a more laser friendly format. The first picture below is the finished pcb layout and the second is the schematic of the circuit. To get the nice monochrome laser friendly picture (pic 3 below) you have to export it from eagle as png.
