 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. |

What level shifter is the best for using on the Picomite? Plasma |

If uni-direction, I like the 74HC4050 74HC4050.pdf |

This works as well for I2C and signals up to few hundred kHz.  Volhout PicomiteVGA PETSCII ROBOTS |

If you only need two channels then I've found that 2 mosfets and four resistors can often be squeezed into spaces that you wouldn't expect them to fit. Mind you, I've put one of those suggested by Volhout between the legs of a Pico. :) For shifting downwards only, a simple potential divider often works.

I used 8 channel bi-direction level inverter with arduino and ili9341 as arduino 5v logic and ili 3.3v their cheap and should be ok to raise 3.3v logic to 5v  |

I use most of the time a voltage devider for low speed or BS170 for 2-way or an optocoupler for 1-way communication. I've a lot of optocouplers lying around and work fine. If you use AI, you lose your mind. |
