Yeah, that’s actually the first thing I do when building a module, is put the vreg and parts on and test to make sure I have 3.3v, so I don’t fry my expensive parts by accident.
But that process doesn’t help if you later apply the wrong voltage to the EXT pins lol
I prob should have made the silkscreen say “3.3v” instead of “VCC”.....

If everything is fine, you should see blue and red LEDs flash simultaneously for ~3 seconds and then switch over to a mode where blue and red LEDs flash alternatively indicating that RN52 is in "Discoverable/Connectable" (Pairing) mode. If that's the case, RN52 is alive and what you should see in your phone's Bluetooth settings is a device named "RN52-XXXX" where "XXXX" is the last four characters of particular RN52 modules BD_ADDR (MAC address).
Thanks Karlis.
She's dead as well. Time to start fresh! I'll update you guys when I get all my new parts in and assembled... And I'll be much more methodical this time. Power track first, check the RN52 off the board, etc. And now I've got more SMD soldering practice, so I should do better this next time. I'll work on the How To document in the meantime.
Thanks for your help guys.
