i2c Logic Level Convertor

This I2C Logic Level Converter - 5V to 3.3V Bi-Directional Module is essentially a tiny buck-boost module that steps incoming signals up and down to match the other components within a project. It is capable of boosting or stepping up 3.3V signals to 5V, but can also buck or step down 5V signals to 3.3V. 

• 5V TO 3.3V Bi-Directional Module
• Signal Voltage Conversion  – 5V to 3.3V OR 2.8V to 1.8V
• High Side I/O Pins – 4 Total (2 Input and 2 Output)
• Low Side I/O Pins– 4 Total (2 Input and 2 Output)
• Required Voltage Sources – 2 (1 for High Side and 1 for Low Side)
