PCB design + validation of my solution(read negative voltage )
Budget: €30 – €250 EUR
I would like to integrate arduino pro mini with other sensors in only one card. the shcematic file already prepared with eagle I need someone only to finalise PCB disign .
in the other hand , add Amp to this circuit in order to read a negative voltage potential , i need to confirm if that solution work properly in order to read negative and positive voltage .
