Logic Level Converter 3.3/5V I2C UART SPI
This logic level converter is designed for connecting two devices with different working voltage. It can safely steps down 5V signals to 3.3V and steps up 3.3V to 5V. The converter has 4 inputs and outputs (lines “1” and “4” are bidirectional, and “2” and “3” unidirectional) and can be used with I2C, SPI, UART, etc. The level converter is very easy to use with all breadboards.
