olewsaa choice has very nice specs a little $$$. I worry a little about encased units as i had one meltdown on me testing. but this look very nice. How would you deal with ground for example a ina219. it is isolated so you don't want to connect the grounds?
I need two types a small type that i can use with esp and nanos. and a larger one that i use with the rpi 3 and 4.
The mean well would work if the power supply is external but this does not work for me as I have the pi mounted in a case that i bolt down. 12 volt is feed by a molex connector. the case has a 12v fan with a simple mosfet circuit to control it. I also don't have anything near it that needs 5V.
I currently use a lm2596 in all of my projects it is barley runs a pi4 and i fine with the 3. and is a little big for esp projects. I am going to try Didier B choice as i like cheap
