Is GPIO linux serial terminal enabled by default?

Mon Jul 01, 2013 2:37 pm

...'cause my usb keyboard has gone on the fritz, and I'm not going to be getting another one for a while. I've got a couple of those HC-05 bluetooth serial modules lying around though, and I thought I might just be able to attach one to the GPIO and bluetooth straight in with no setup, using my phone or pc-with-a-dongle or whatnot.

I'm not really a power user, but I thought the question would be best suited here...
note: I may or may not know what I'm talking about...

Yes by default it is. And when the pi boots up it will print all the boot messages to the serial out.
There is loads of good info here: http://elinux.org/RPi_Serial_Connection

Good luck!

The HC-05 consumes 50mA and that is also the max power that can be supplied by the 3V3 power pin on the RPi.
Should be OK but you are pushing it right to the limit.
Unless specified otherwise my response is based on the latest and fully updated Raspbian Stretch w/ Desktop OS.
