Wide spectrum impedance meter with AD5933 TI Stellaris ARM CortexM.

My first commercial hardware project. I designed the custom PCB shield with the AD5933 impedance measurement chip and the AD8646 rail-to-rail operational amplifier. I produced the PCB shield using a UV resin.

I also wrote the firmware for the device as well as design the UI in LabView.

Main features:

• 12 bit measurement resolution
• 1 Msps rate
• AD5933 impedance measurement chip
• AD8646 rail-to-rail op-amp
• TI Stellaris LM3S8962 Ethernet+CAN motherboard
• UI in LabView
