The scheamtic is complex but I've tried to separate it into individual parts for voltage measurement, resistance, current and so on. You could solder each part one by one and test them out for degug. Soldering 0402 components is not that difficult. Aslo, if you don't use the BT module, you don't have to solder it neighter the 3.3V regulator. Follow the values below.
