The Variable Voltage Supply reference design takes an input voltage and converts it to a lower output voltage, and it's readout can display both voltage values. We've modified the LM2596 voltage display module from China LC Technologies to be more user friendly. We've added a 2 wire dupont input with reverse polarity protection and black & red output wires with Alligator clips. We want to share these files with you so you can create your own!
