You can power the MAX3232 from 3.3v, so just feed that into the Vcc pin, and it will work.
The RS232 output will still be ±5v even powered off 3.3v

Thanks for the advice! I think I will put the breakout and bare module footprints on the PCB, to give me the most flexibility. Now that I have the breakout, I can see that it would be hard to desolder w/o hot air. Good idea about putting components under it!
However, now I have a different issue. I can only perform some of the set commands. I’m not sure why only certain ones work. I went down the list and set everything to their defaults, here’s the serial log: http://pastebin.com/t8Gb4Hg3 . Am I missing something obvious? Why are some of them giving an ERR?
Is it possible to desolder the module from the breakout board?
I’m in the process of creating a custom PCB, and would like to prototype with the breakout board, then remove to module and mount it directly on the PCB once I fabricate it.
However, looking at the PCB, there are 6 ground connections underneath the module. Are these soldered to the breakout PCB? Or are all soldered connections accessible?

Is the add to cart button not showing up for anyone else?
The “Dings and dents” page says it’s in stock and there was a new product post on it.
I really want to get my hands on one!
