- Product Description Solve I2C Address Conflicts Eliminate the "same-address limitation" by routing I2C commands to specific channels (0-7) via a single control byte, enabling scalable sensor networks. Technical Specifications Chipset: PCA9548A/TCA9548A (pin-compatible) I2C Address Range: 0x70 to 0x77 (hardware-configurable) Logic Levels: 1.65V-5.5V (3.3V/5V tolerant) Clock Speed: 400KHz max Channel Count: 8 bidirectional buses Key Functionality Channel Selection: Send a byte (0x01-0x80) to activate one channel. Example: 0x01 for Channel 0, 0x02 for Channel 1. Cascading Support: Chain multiple multiplexers (e.g., 8 boards → 64 devices). Hardware Integration Breakout Pins: VCC, GND, SDA, SCL, A0-A2 (address selection) Dimensions: 25.4mm × 20.3mm (1" × 0.8") Compatibility: Works with I2C libraries (Arduino Wire, Python SMBus) Typical Applications Multi-sensor environmental monitors (e.g., 8+ BME280s) Robotic sensor arrays (LiDAR/TOF clusters) Industrial equipment with redundant sensors Automated test jigs for I2C devices Package Includes 1 × PCA9548A/TCA9548A Multiplexer Breakout Board

8-Channel I2C Expansion: Connect up to 8 identical-address I2C devices (e.g., sensors) to one microcontroller via addressable channel selection. Wide Voltage Compatibility: Operates at 1.65V-5.5V, supporting 3.3V/5V logic systems like Arduino/Raspberry Pi without level shifters. Configurable Addressing: Set multiplexer base address from 0x70 to 0x77 via jumpers, enabling 64+ device control with multiple boards. High-Speed Communication: 400KHz max I2C clock frequency ensures rapid data transfer for real-time sensor networks. Breadboard-Ready Design: Pre-soldered headers for prototyping; integrated pull-ups/pull-downs simplify circuit integration.
