پروتکل هایی نظیر UART/IIC/1-WIRE/SPI و برقراری ارتباط و انتقال داده ماژول ها با سطح ولتاژهای متفاوت می باشد. همچنین از این ماژول می توان در ماژول بلوتوث، ماژول وای فای، انواع مختلف ال سی دی ها،  ارتباط های I2C، ارتباط های SPI و انواع ماژول های فرستنده و گیرنده استفاده کرد.
از جمله ویژگی های این ماژول دارا بودن نشانگر تغذیه و محافظت اتصال برعکس با جریان کمتر از 150 میلی آمپر است.
رابط کاربری این ماژول از طریق پورت SPI فراهم می گردد و محدوده ولتاژ آن از 2.8 ولت تا 6 ولت با حداکثر جریان خروجی 1.2 آمپر است.

Description:
If you’ve ever tried to connect a 3.3V device to a 5V system, you know what a challenge it can be. The logic level converter 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.
You can use this module to connect two devices of different digital voltage levels. For example: connecting an Arduino (5V device) to an ESP8266 (3.3V device).
This module requires you to supply it with power from both the higher voltage level and the lower voltage level. Connect the higher voltage source to pin "HV" and its ground to pin "GND" near the "HV" pin. Also, connect the lower voltage source to pin "LV" and its ground to pin "GND" near the "LV" pin. For example, if you were connecting your Arduino (5V signals) to an ESP8266 (3.3V signals), you would connect the "HV" pin on the module to the 5V supply pin on your Arduino and the "GND" pin near the "HV" pin to the "GND" pin on your Arduino. Then, you would connect the "LV" pin on the module to the 3.3V power source that is supplying power to the ESP8266 and connect the "GND" pin near the "LV" pin to the 3.3V power supply's ground. You would then connect the signal pin from your Arduino to one of the signal pins on this module (for example, pin "HV1"), and then you would connect the desired signal pin on the ESP8266 to the corresponding pin on this module ("LV1" if the higher voltage signal is connected to "HV1").
