Stereo digital audio spectrum analyzer V4.0


This is a stereo upgrade of previous version 3.x.

These boards can be bought from http://devboardshop.com

This version has multiple changes from the previous version, like:

V 4.0A is a version with 18 Bands + Two VU meters for right and left channels.
  1. Can handle stereo signals.
  2. Display format is 18+1+1( to display 18 bands of frequencies and Left Right signal level) .
  3. USB adapter for easy upgrade.
  4. Dedicated RTC with battery back-up.
  5. Added two usart connectors to create cascade spectrum analyzers( to create large display from boards like this ).
  6. A microcontroller twice faster that previous and multiple hardware advantages that increase speed of signal processing and display rendering.
Down I posted two photos with new board design.





V 4.0B is a version with 20Bands.
