Thanks for the info. I’ve been looking for “inexpensive”, and I want to make a number of boards for my project. I suppose if I’m making my own board, the cheapest thing is to make my own Arduino circuit.
I also want to be able to run off a lipo, but I’m also running an led matrix, which most controller chips for led matrix’s are 5 volt (though the led matrix itself wants something like 2.7 volts.)
Choices, choices…
