I got this presumably cloned logic level shifter to try to wire my Nano to an ILI9341 TFT screen. I previously got the screen working using resistors to divide the voltage. When I tried to replace the voltage dividers with the level shifter, I have had no success.
I tried to make a simple example, but the multimeter reads 0 when touching A1 to ground (I have no idea how to use a voltmeter, and also do not know if this example is valid or not). B1 and VB read ~4.6v and VA reads 3.3v.
I have tried connecting OE to ground, 3v3 and 5v. I'm pretty stuck, any help appreciated, thanks!
