i've discovered 5v (arduino) to 3.3v (esp8266) serial requires a logic
level shifter.
i have a max3243 <http://www.ti.com/lit/ds/symlink/max3243.pdf> with no
idea how to use it.
anyone know how to use a Multichannel RS-232 Line Driver/Receiver or
know a good circuit schematic that converts 5v-3.3v logic?
thx
