    simple system but useful cheap good performance everything works fine I recommend to all who use modules with different voltages

    4 channels converter 5V to 3.3V and 3.3V to 5V : you must have 5V and 3.3V supply on the board to perform that.

    Necessary if you want to interface different logic levels devices, for instance serial communication between Arduino and Raspberry; very good!

    These parts are cheap, but work very well. They do exactly what you would except a bi-directional logic level convertor to do, they let your 3.3V and 5V parts communicate without troubles. More than quick enough for 99% of all projects and the remaining 1% will need very specialised parts already.

    If you use digital addressable LED strips this logic converter makes the signal more reliant.

    It actually is only able to really convert 2 channels (so for example 1 I2C connection), but for the rest they are working fine

    Chip and robust tiny PCB, you have not to do this convertes - you have just to purchase it.
