  • Great solutions for 3.3V development boards!

    I recently bought an Arduino Due board, of which it's GPIO pins operate at 3.3V, not 5V as other boards do. Instead of improvising a level converter myself, I decided it's best to buy a already made and tested one. Even though it only has 4 bidiractional ports, it's more than 0 that I had. To use it, you only need a 3.3V and 5V supply, and that's it! A red SMD led confirms power is present, so you can start using 5V signal on a 3.3V pin (or vice-versa).


    None. The fact that it's pins aren't soldered is actually an advantage, considering that some would wish to solder 90 degrees ones, or the cables directly, depending on their applications.


    None so far.


    Great little level converter!
