Connected objects require adjustable voltages and very low current measurement during its development. I propose a card that goes on an Arduino Leonardo.
- 5 Volt power supply from USB port via Arduino Leonardo
- 0 Volt to 5 Volts at 0.05 Volt pitch with memory
- Software shutdown of the power supply if the current is greater than 20mA
- Display of selected voltage
- Display of current from 20mA to 0.5μA
