Could someone explain the voltage translation "Magic" that is happening in the circuit in the link below?
The YRPBRL78G13( blue on the left ) is a 5V design and the cc3000 module is a 3.3V design.
I can't understand how the arrangement of LDO and pullup (pulldown?) resistors would achieve voltage translation.
I've tried simulating this, and as far as I can tell this shouldn't work.
All help is appreciated!
