Logic Level Converter

Logic level converter is mentioned for the sake of completeness. You will need it only if you use additional 3.3V sensors such as accelerometers.

• A level shifter is needed for 5V devices to interface with other lower voltage circuits

• Typically required for interfacing sensors which operate on 3.3V

• For bidirectional systems (signals flow both ways) a level shifter must also be bidirectional

• Level shifters are usually implemented using MOSFETs
