Cool, thanks guys! Yeah, the gate drivers worked well on the XpressoSmoothie board, but some recent changes in Smoothie locked down the use of a bunch of pins to I2C and SPI, and unfortunately, they were pins I assigned to steppers. Eventually, I'm going to update the board to fix that, but I think it's going to end up being a tangled mess. So, for the mean time, I wanted to hack something together out of parts I had laying about, and one of those things was a level shifter.
On a related note, the guy who helped me out (wolfmanjm) mentioned that another Smoothie dev tested the AOT240L and it worked straight off the pin at 3.3V.
