7Semi- TCA9543A I2C Multiplexer Board – 2-Channel I2C Bus Switch

    The 7SEMI TCA9543A I2C MUX Board is a low-voltage, 2-channel I²C bus switch designed for applications where address conflicts or I²C expansion is needed. Built around Texas Instruments’ TCA9543A, this board allows a single I2C master to control multiple slave buses with independent interrupts and reset support.

    With support for 1.65V–5.5V logic, voltage-level translation, and hot-swap tolerance, this compact breakout is ideal for sensor networks, multi-sensor gateways, debugging tools, and industrial monitoring.
