Vbus to TTL converter
Version 1 - Last update: Jun 5, 2016

This circuit converts the Vbus data to TTL levels so that it can be used as input to an Arduino

This is fully described by its author here: https://piamble.wordpress.com/2014/06/17/home-energy-centre-using-raspberry-pi-and-nook-simple-touch/ As designed there is a voltage divider in the output in order to make the levels compatible with the Raspberry Pi (0-3V). However, I have chosen to omit that divider and, if required, use a better logic level converter on a separate PCB.
