Need some quick guidance.
I will be installing my Uno in a small electrical enclosure, but I am not sure the best way to power everything.
I have the Uno (of course) and 3 other devices that are 5 volts. With the possibility to add more 5v devices in the upcoming weeks.
It seems the best voltage for the Uno is around 7-9 volts DC, and I can input that into the Vin pin. But how to I supply 5 volts to my other devices? I do not want to power the Uno from the USB port either. It would be great if I could keep everything hardwired.
I did find some LM2596 power modules, which I thought of installing multiple modules feeding them with one 24VDC power supply, keeping all the GNDS tied together.
