I found that in the core, there was 7805 voltage regulator for 5v, there was no 3.3v edition, also there was a down-pull menu, it could not be selected. And, when I selected 7805, I couldn’t modified it’s pins arrangement as UTC1117.
7805 pins: In Gnd Out
UTC1117: Gnd OUt In
There was a 3.3v in Sparkfun-PowerIC, but the mark “78xxl” couldn’t be changed.
Looking at that webpage it’s clear that it’s a surface mount component on a breakout board that is breadboard friendly. I’ve seen SMD devices on breadboard friendly breakout boards before that had the actual pcb SMD footprint.
Hey, take a look at that part, and if it won’t work for you, explain why it won’t work for you. Maybe someone can fix it to your needs…
