    alright, did you used one one with input filtering? Then what you have used to test the circuit? like connect between power supply and a load?

    @@oPossum.... i tried to build the circuit as it is shown in the vam_meter_schematic picture file. but the LCD do not show anything. may i know if the capacitor u used in this is a ceramic ones or electrolytic capacitor? The back light is working but it did not display the power up logo---> msp430 and INA219

    One more important question is...... soldering the INA219 will not damage the chip? I'm new to SMD soldering.

    hmmm..... i see. Is it possible to use a CT current sensor for this circuit? Or a Halls effect current sensor?
