Logic Level Converter 3.3V – 5V Bi-Directional

Product Overview

Many devices and protocols use 3.3V logic including I²C and SPI. This logic level converter converts 5V from microcontroller boards like the Arduino UNO to 3.3V and back for use with these systems and devices. Each board has 4 separate channels for converting voltage levels back and forth. It can even be used with 2.8V and 1.8V devices.

To use the converter, start by connecting the high voltage reference (EX. 5V) to HV and connecting the low voltage reference (EX. 3.3V) to LV. Then you can connect your high voltage device to one or multiple of the high side pins, and your low voltage device to the same pins on the low voltage side. Ground can be directly connected from device to device and does not need to be connected to the converter.

Note: This item comes with 12 male pin headers not soldered. If you would like the soldered version, you can find it here.
