AJMRTC PCA9306 I2C level shifter module solves voltage mismatch issues between different logic level I2C devices. It enables safe bidirectional signal conversion between low-voltage microcontrollers and 5V IIC sensors or peripherals. No direction control signal is required; the chip automatically detects and switches signal flow. Each board breaks out all pins to through holes for simple prototyping. Great for Arduino, Raspberry Pi, STM32, sensor modules and embedded I2C communication projects.
