Hi every one i am trying to interface arduino uno and TDC GP22 for laser range finder application. I am using SPI interface to connect GP22 board. Arduino uno gives 5V output and SPI needs 3.3V. In order to communicate bidirectional do we need to have any logical level shifiting . can any one tell me how to do this and what ic we need to use

Use arduino nano/micro? They are 3.3v I believe
