## Description

The SparkFun Qwiic Mux Breakout uses the TCA9548A to provide 8 independent I2C channels, solving the common problem of multiple sensors sharing the same address. Simply route each device to its own channel and communicate with all of them on a single bus. With 8 configurable addresses (via solder jumpers), you can daisy-chain up to 8 mux breakouts for a total of 64 I2C channels. The board operates from 1.65V to 5.5V and uses Qwiic connectors for solderless, polarised connections. Key Features 8 I2C Channels – Connect up to 8 same-address devices TCA9548A IC – Reliable I2C multiplexer with wide voltage range 8 Configurable Addresses – Solder jumper selectable (3 ADR jumpers) Qwiic Connectors – Solderless, polarised I2C connections 1.65–5.5V Operation – Compatible with 3.3V and 5V systems Cascadable – Up to 64 channels with 8 mux boards Specifications IC: TCA9548A I2C Channels: 8 Default Address: 0x70 (configurable 0x70–0x77) Operating Voltage: 1.65–5.5V Connector: Qwiic (JST 1mm, 4-pin) Ideal For Using multiple identical Qwiic sensors on one bus Expanding I2C address space Multi-sensor projects with address conflicts Large-scale I2C sensor networks Package Contents 1× SparkFun Qwiic Mux Breakout – 8 Channel (TCA9548A)
