The Bi-Directional Logic-Level Converter is designed to convert between two different logic voltage in data lines, and allows components with two different logic and operating voltages to communicate with one another (e.g. a 5V Arduino Uno communicating over I2C with a 3.3V module and vice versa.)
Not using logic level converters can create problems in your system from producing nonsense information, to permanently damaging your boards and rendering them unusable.
To use this module, simply connect the operating voltage source and GND of both components (this acts as voltage references for both boards) to the converter, and then connect your data lines to the module. The module will automatically convert between the two logic voltages.
Comes with 2x 5-Pin headers. We also provide soldering services if you require headers pre-soldered.
