Connecting a 3.3V device to a 5V system is a challenge.
The bidirectional logic level converter is a small device that safely drops the signals from 5V to 3.3V and increases 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 it can successfully set its high and low voltages and go up and down between them safely on the same channel.
Each level converter has the ability to convert 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 sources of voltage (high voltage and low voltage) that your system is using.
