The updated schematic for the AVRCore module (rev 1.2) shows that it requires regulated 3.3vdc power but the documentation on your website states that it takes regulated 5vdc power. I just got my Uzebox and I wanted to make sure first before I apply 5vdc and end up blowing it up.
I think they just added support for 3.3V… By default, you would still power it with 5Vdc.
(R27 has a value of “DNI” or most likely “Do Not Include”)
You should still ask someone what to put in the footprint of R27 for 3.3V operation and report back here, could be just a short…
What ever you do, don’t let out the pretty blue smoke.
