      Anyone have any pointers to why a '3p3' 3.3V output on 500mA would not power a LoPy? I connected it and it wouldnt com on.

        Can you describe how it's connected in more detail - both power and others.

        Also do you see any output on the serial console?

          @jmarcelino Wen I connect it on the dev board the LED comes up after a few seconds. When I connect it to my 3.3v source, nothing happens.

          This should be enough power right?

            do you have anything else connected when powering from the 3.3v source?

            Also what is the 3.3v source exactly?

              @jmarcelino Basic connection. LoPy's 3v3 and GND to source's 3p3 and GND. I checked with multimeter that the source spits out right and it it all looks fine. I think I am actually getting 1A out of my source. Accodring to spex the device gives: Regulated 3.3-volt, 500mA

                @MarcusKirsch I found the 5V pin (doh!) all good all running.
