If you’ve ever tried to connect a 3.3V device to a 5V system, you know what a challenge it can be. The SparkFun bi-directional 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.

如果你曾經嘗試過3.3V器件連接到5V系統，你知道它是怎樣一個挑戰。所述SparkFun雙向邏輯電平轉換器是5V的信號安全地進行降壓至3.3V與台階3.3V至5V的同時的小型裝置。該電平轉換器也適用於2.8V和1.8V器件。真正從我們以前的版本分開這個邏輯電平轉換器是可以成功地設置高和低電壓，並加強上下之間安全地在同一個通道。每個電平轉換器具有兩個輸入端和提供給每個側面的兩個輸出的高側變換4個引腳4上的針腳低側的能力。
電平轉換器是非常容易使用。該板需要從你的系統使用的是兩個電壓源（高電壓和低電壓）供電。高電壓（5V為例）的'高壓'腳，低電壓（3.3V為例）為“LV”，和地面從系統到“GND”引腳。
