i recently purchased a PmodIA board to perform some bioelectrical impedance measurements. The idea is to use it at a fixed low frequency (around 15 Hz) and control it with an Arduino microcontroller. I have little experience in this field and was wondering if someone has some examples/codes/guides I could use to start working with the PmodIA. I found an AD5933 Arduino library in github but it is not very useful. Also, is the Arduino the best way to control this board? Are there better options?

Hi @Victor C,

The Pmod IA was retired some time ago so there isn't a lot of support around it available. There was also some (in my opinion) inherent user friendliness issues with the embedded AD5933 chip and I was never able to find a C based library that correctly manipulated the registers. The best material I can point you towards is this thread: https://forum.digilentinc.com/topic/4375-pmodia-returning-incoherent-impedance-values/?sortby=date.

I'm sorry I couldn't be of much more help.
