Measuring Unit for the Lab bench power supply

Thit PCBA can measure Voltage, Current, Power and Amount of power. I use an Atmega328 with an LCD Display to process the data and show the results. For the measurement, I use a 13-Bit ADC. With this ADC I get a resolution of 7,3mV per step, with Multisampling the accuracy increases. The current is measured with a 0.1 Ohm shunt. The Voltage difference is amplified with a Rail-to-Rail operational amplifier.
