Hello. I have a sparkfun pro micro 5V connected to usb and I would like to power a bluetooth hc05 module. I read that I can do this from vcc pin and I see with multimeter that it has 5v, so I will connect it there. But I would like to ask, is it possible to power the external module from raw pin? With multimeter I see 5v there too. (I know that raw and vcc may be used as inputs, moreover vcc may be used as output, what about raw?) Thanks!
Quick Google, the schematic: http://cdn.sparkfun.com/datasheets/Dev/Arduino/Boards/Pro_Micro_v13b.pdf
So Raw is connected to the USB power via a diode. You could use raw as an output then but why would you?
Thanks for the answer! I asked for knowledge!
