The SparkFun FM board plugs into J1 connector (marked FM - left hand side) on my printed circuit board.
If you are interested in this project and want the printed circuit board please send an e-mail to the following address and put 'FM radio' in the subject line. The printed circuit board costs £12 (includes VAT and postage to UK), I will e-mail you with information on ways to pay. Included with the circuit board are components that are more difficult to source or where the circuit board is designed for a specific component (e.g. on/off switch).
