Although I have successfully designed and ordered PCBs with FET based level shifters, just for a change I would like to build a Wemos D1 mini interface which has instead a two or four channel level shifter based on a surface mount IC. I checked LCSC and found some that would work, but just thought I would ask if anyone else has used a particular dual or quad buffer chip and which one you recommend. I know I didn’t mention but of course I want to translate the 3.3V GPIO to the 5V world if that were not obvious…
Have you seen this?
Thanks! No I did not see that.
