Build instructions for the tiny spectrum analyzer uploaded to file area


 

I uploaded a small document describing how to connect the various modules of the tiny spectrum analyzer.
You MUST use a 3.3V compatible Arduino (such as zero or due or compatible). Arduino code and a small windows executable for controlling the tiny spectrum analyzer are also available in the files area

Great work.? Thanks for sharing.? I see an electrolytic cap in your picture that I can not quite see what it is connected to.


 

Its a low ESR cap for extra decoupling of the 3.3V. Not sure its needed.

Hi Erik,
Re. the build instructions.

Connect the receiver module to D1and the LO module to D5 of the Arduino(WARNING: You MUST use a 3.3V compatible Arduino)

Should that be 'Connect the receiver module to D0' rather than D1 ?? (const int SI_nSEL[2] = { 0,5 };)

Thanks !
Jim


 

Ah, yes. Will correct
