From the project

DIY logging voltage/current meter

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 supposed to have the same functionality as much more expensive dataloggers, with the added benefit of the ability to change the firmware to add more functions.
