Oops, I meant, do I have to set up BJTs and pull a pin to Vcc if the cable's input (input to my board, output from the cable) is 3.3V.. Output pins would be the other way
The 2.57 is suspicious, ~ a diode drop below 3.3. The Eval1 regulator has a 2 V dropout
voltage, are you feeding it > 5.3 V ?
Ah, using a 9V to power the board. I assumed that the regulator would wrk with it.
Consider posting the project and a schematic for the forum to look at.
