If you have ever tried to connect a 3.3V device to a 5V system, you know what a challenge it can be? A bi-directional Level Converter- 4 Channel 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 successful

How to use:

1. High voltage (5V for example) to the HV pin
2. Low voltage (3.3V for example) to LV
3. Gound from the system to the GND pin.

1. Mutual transform between 5V TTL and 3.3V TTL
2. Four channels of logic and high voltage low voltage logic can two-way transform
3. Portable and lightness, with 2 rows 6 pin contact pins
4. Level Converter- 4 ChannelCompatible with the bread plate, can be used directly put on the breadboard
