PCA9306 Bidirectional I2C/UART Level Shifter Breakout Board Module, 3.3V and 5V Level Translator

The PCA9306 level conversion module is a bidirectional voltage converter for I²C/SMBus interfaces. It supports connections between devices with voltage levels from 1.2V to 5V, including 3.3V MCUs (STM32, ESP8266, Raspberry Pi) and 5V sensors (OLED, BMP180, MPU6050). The module incorporates the TI PCA9306 chip, supporting 400kHz high-speed I²C communication. It features automatic bidirectional switching without external direction control signals. It allows bidirectional voltage conversion within the 1.2V to 5V range, supporting configurations such as 3.3V and 5V. The dual-channel design converts the two I²C signal lines, SCL (clock) and SDA (data). Physical specifications include an integrated PCB with straight-in pin headers. The compact breakout board design accommodates breadboard or jumper wire connection. The component enables operation between microcontrollers and sensors. Specifications: Chip Model: PCA9306DCUR (TI) Input Voltage Range: 1.2V ~ 5V (VREF1 ≤ VREF2) Maximum Frequency: 400kHz (I²C Fast Mode) Conversion Direction: Bidirectional Automatic Switching Interface Type: I²C (SCL + SDA) Operating Temperature: -40°C ~ +85°C Pin Definition: VREF1: Low voltage side power supply (such as 3.3V) SCL1: Low voltage side I²C clock line SDA1: Low voltage side I²C data line GND: Ground SDA2: High voltage side I²C data line SCL2: High voltage side I²C clock line
