Making my Arduino controlled RDA5807M FM Radio

This video shows the assembly of my Arduino controlled RDA5807M based FM radio. The details are covered in other videos: - Connecting the RDA5807M FM Radio IC to an Arduino, including a demo of the radio in operation: https://www.youtube.com/watch?v=2j1hX4uzkQ8 - Trying out a PAM8403 audio amplifier module https://www.youtube.com/watch?v=oB-k0tA1G2M In this video I: - create a break out board for the RRD-102 module containing the RDA5807M. The module has castellated vias at a 2mm pitch. I use some stripboard to break out the connections to 0.1in pitch suitable for breadboarding. - assemble a small logic shifter board. - use hot air to remove a 5V LDO regulator and replace it with a 3.3V regulator. - put all these things together with an Arduino Pro Mini and a PAM8403 amplifier module in order to create an FM radio.
