Ask the engineer to help me choose the board.

Hi,

I need to measure the current and voltage generated by the piezoelectric electrode. The magnitude of the current is about μA or NA. I don't know the magnitude of the voltage. Can you recommend it to me based on the magnitude of the current? I currently have cn0407 and CB1Z. I want to know what board I need to measure voltage and current. Please recommend a set for me.

Best wishes!
