Hi folks, I’m looking for some help with the following component https://shop.pimoroni.com/products/adafruit-4-channel-i2c-safe-bi-directional-logic-level-converter
I was looking to use with a teensy 3.2 to drive some 12v WS2811 LEDs
If I use 5v to supply the LEDs they work correctly, but when I try a 12v supply, they then begin to flicker. I had put this down to the logic level of the teensy being 3.3 not 5v so thought this logic level converter would help.
I had assumed I could just connect up the 3.3v supply to the LV and 5v to the HV and then connect the teensy to one side and the LEDs to the other, but this doesn’t appear to work. I also noted that the pins for the converter that are not connected all appear to be high at all times - e.g the lv side are all 3.3 and he hv side are all 5v. Are they high by default?
Any help or guidance would be much appreciated as I have only a few days to turn round this project
