 Notice. New forum software under development. It's going to miss a few functions and look a bit ugly for a while, but I'm working on it full time now as the old forum was too unstable. Couple days, all good. If you notice any issues, please contact me. |

I made my own from a common circuit on google. Works nicely and you can simply pick bits of it up and reproduce to do level-shifting on any width. Resistors are matched to whatever pull-up you want, 10K, 4K7 whatever...  That said, rtg boards are very cheap so if you can match the size I would go that way - I just wanted a very small 3-way shifter hence this board Edited 2021-06-02 16:11 by CaptainBoing |
