Hello,
I can do this work for you. Please, send me more information.
AD5934 is designed to measure impedance 1 kilohms to 10 megohms, from 100 ohms to 1 kilohms with additional circuit. Under these resistances four-wire connection method does not gain in precision. If you want to measure small resistance need another chip.
I develop concepts, design circuit, PCB and software for devices on Microchip and Atmel microcontrollers (C, C++, Arduino). You can see some my works in my portfolio.
Regards,
Alexey
