The Logic Level Converter Board safely translates digital signals between devices operating at different voltage levels, making it ideal for connecting 3.3V and 5V microcontrollers, sensors, and peripherals.
This Logic Level Converter Board module gives us a translation of logic level between two signals. In layman's terms, if we take a signal with logical "unit" on 5V convert into a signal which logical "unit" has on 3.3V this module will help us.
Something like this is useful in this case if we want to achieve communication between two devices from whom one works on 5V and the other on 3.3V, or any other combination of voltages. Directly connecting we would "burn" a device that works on 3.3V and a module gives us to avoid that.
