7Semi PCA9306 I2C Bidirectional Voltage Level Translator Breakout Board The 7Semi PCA9306 I2C Bidirectional Voltage Level Translator Breakout Board is a compact and efficient PCA9306 voltage level translator designed to safely interface I2C and SMBus devices operating at different logic levels. Supporting voltage translation from 1.2V to 5.0V, this board enables seamless communication between low-voltage sensors and higher-voltage microcontrollers without manual direction control. As a dependable I2C logic level converter, it delivers minimal signal delay and stable bidirectional data flow, making it ideal for robotics, industrial controllers, embedded systems, and DIY electronics projects requiring precise mixed-voltage I2C communication. Allowable Voltage Level Translation The breakout can transfer voltages ranging from 3.3V to 5V. VREF1 (Low Side) VREF2 (High Side) 1.2V 1.8V, 2.5V, 3.3V, 5V 1.8V 2.5V, 3.3V, 5V 2.5V 3.3V, 5V 3.3V 5V Features: Wide Voltage Range Support: Operates between 1.2V and 5.0V, accommodating a wide range of components. Dual Bidirectional Channels: Translates both the SDA and SCL lines for complete I2C compatibility. I2C and SMBus Protocol Support: Fully compatible with regular and fast-mode I2C devices, as well as SMBus peripherals. No Direction Pins Required: Signal direction is automatically detected for easier design. Low propagation delay: A delay of less than 1.5ns maintains data integrity at high speeds. 5V Tolerant I/O Ports: Securely links 5V signals to lower voltage devices. Compact and simple to use: ideal for embedded applications, prototyping, and compact systems.
