This battery-powered logging volt/ampmeter was made with the intention to easily get .CSV files filled with voltage/current/power measurements on a SD-card to plot and use this data further. It is ...

It used a resistor divider and was showing 1 for 0.075mV reading on pin 2 of STM8. I managed to turn it into an amp meter, by shorting the top resistor in the resistor divider and using a 0.075mOhm ...
