This is a small device that safely steps down 5V signals to 3.3V AND steps up 3.3V to 5V at the same time. This level converter also works with 2.8V and 1.8V devices. What really separates this Logic level converter from our previous versions is that you can successfully set your high and low voltages and step up and down between them safely on the same channel. Each level converter has the capability of converting 4 pins on the high side to 4 pins on the low side with two inputs and two outputs provided for each side.

The level converter is very easy to use. The board needs to be powered from the two voltages sources (high voltage and low voltage) that your system is using. High voltage (5V for example) to the ‘HV’ pin, low voltage (3.3V for example) to ‘LV’, and ground from the system to the ‘GND’ pin.

    Works as expected and pins are also included.
    Spacing is correct for breadboards/soldering with the standard 100mil / 2.54mm grid.

    nice unit… uses 4 FETs (instead of 2 FETs and a voltage divider on the down conversion side like a lot of others)… super useful if you want to run your atmega328 at 16MHz and interface with 3.3v devices…

    Very good module for arduino projects if you need to convert 5V signals to 3.3V and viceversa
