FM Radio With Si4703, Arduino Pro Mini and 3.3V Large LCD

Around this time last year I published an Instructable just like this one where I used an Arduino Uno with the Si4703 evaluation board, a logic level converter and a 5V LCD to make an FM radio for my jukebox build. I decided the circuit was untidy and needed a bit of an upgrade, it also took up a lot of space in the jukebox. So I decided to use a smaller Arduino which has 3.3V logic to simplify the circuit a bit (the logic level converter is no longer needed) This Instructable is therefore about a 3.3V logic version of what I had done before.”
