5 PCS IIC I2C Logic Level Converter Bi-Directional Module 5V to 3.3V for Arduino

Description

--The bidirectional logic level shifter is a small device that safely steps down the 5V signal to 3.3V while boosting 3.3V to 5V. --The level shifter is also suitable for 2.8V and 1.8V devices. --You can successfully set the high and low voltages and safely move up and down on the same channel. --Each level shifter is capable of converting the high-end 4 pins to the low-end 4 pins, providing two inputs and two outputs on each side.
