So I spent my last week end working on a full 3V3 to 5V level translator for my Raspberry Pi®. What I mean by "full" is that all the RPi GPIOs (17 lines) have their own translator. I didn't find such a board on the market so here it is!
"The whole project relies on mechanical design, electronics, software and the great opportunity to create a machine with parts from my 3D-printer. I have worked with this project to and from for several years, but now in recent months the project has had an exciting development, and as I write in the title... Now the magpies work as garbage collectors, payed with food!"
