Logic Level Converter Bi-Directional 4-Chanel 5V-3V
Some sensors are not compatible with your MCU in terms of its logic level. This module helps you with converting the logic level so that they could communicate adequately.
This logic level converter uses 4 MOSFET to read and convert four channels of 3.3V and 5V logic.
By bi-dimensional, this can handle UART, SPI, and I2C communications conversion from 3.3V to 5V and vice versa. This module needs 3V to 5V of supply.
You could use this to MCUs that have 3.3V or 5V logic, which means you could use almost all MCUs and Arduino.
