We built a board that has a MAX3013 chip for level converting. Also a MAX3387E for RS232 comms.

I think even a level converter like this one should work:

I am observing a TBOI/OVERO board with a scope and pin 17 appears to
send 0v, 1.8v when toggled with GPIO. It is interfacing with a CMOS/PIC
that requires (I think) a 2.5V  threshold to go from low to high.
I want to use an IC Buffer or inverter such as the CD4049UB, CD4050B.
Sound like a good idea? Interested in what others do.
