I switched over to using and Arduino Due from an UNO and now have to change the voltage requirements so I can send my inputs to my stepper drivers which are +5V.
I was looking at this (TXS0108E 8 Way Level Conversion Module) and it seems straight forward with the A pins at 3.3V switching to +5V on the B pins, I supply a +5V and 3.3V power to each side of the chip. The thing that is holding me up is the OE pin and what needs to go there, I have seen some wiring it to 5V and some going to GND with it but none of them are driving stepper drivers. There are also requirements for a pull down resistor thrown in there to really confuse me so hopefully I can get someone to point me in the right direction.
spec sheet for converter is here.
here is how I think it should go,
DUE -> txs0108 -> driver
3.3v -> VCCA
5v -> VCCB
GND -> GND
GND -> OE ???(or leave open)
Pin 3 -> A1 -> B1 -> Driver
Pin 4 -> A2 -> B2 -> Driver
But this leaves out the resistors and I've seen some diagrams on google that show capacitors on the power supply lines.
