10 PCS TXB0104 4 Channel Logic Level Converter Module

Description:
It is a 4-channel or 4-bit logic level converter that is great for interfacing sensors or 3.3v logic components with 5v logic level microcontrollers. This unit will do the level shifting required to allow theses device to communicate without burning out each other. On the right side, Vb is the input voltage reference of 5v, whereas Va and OE are the input reference of 3.3v. The common ground is applied to GND and B1 to B4 will serve as digital input 5v to be converted into 3.3v from A1 to A4 or vice versa. If you want to convert an analog signal you require an op-amp.
However, if you are using it for I²C communication we would suggest looking for a dedicated I²C logic level converter as this board is not capable logic level conversion of pull up the line of less than 50kΩ.
