Hi All,

This is my first post here so I am looking forward to engaging with the community! I am an undergraduate student who started pursuing a summer internship at a university research lab. The lab members mostly work with sensor development and my project is to help develop an interfacing circuit for one of their sensors. It is based on impedance measurement of the sensor at different frequencies and the immediate goal is to interface this sensor with a circuit that can sweep the applied frequency from 100 Hz to 100 kHz while recording the measured impedance at each frequency point. My supervising professor asked me to explore the possibilities with AD5933 (https://www.analog.com/media/en/technical-documentation/data-sheets/AD5933.pdf). I was trying to look for breakout boards but there seem to be none with good documentation and some are obsolete (https://digilent.com/reference/pmod/pmodia/reference-manual).

Given the circumstances, I would be grateful for some help with starting this work from more experienced community members. Thank you for your time!
