Simply route each device to its own channel and communicate with all of them on a single bus.\n\nWith 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.\n\nKey Features\n\n\n8 I2C Channels – Connect up to 8 same-address devices\n\nTCA9548A IC – Reliable I2C multiplexer with wide voltage range\n\n8 Configurable Addresses – Solder jumper selectable (3 ADR jumpers)\n\nQwiic Connectors – Solderless, polarised I2C connections\n\n1.65–5.5V Operation – Compatible with 3.3V and 5V systems\n\nCascadable – Up to 64 channels with 8 mux boards\n\n\nSpecifications\n\n\nIC: TCA9548A\n\nI2C Channels: 8\n\nDefault Address: 0x70 (configurable 0x70–0x77)\n\nOperating Voltage: 1.65–5.5V\n\nConnector: Qwiic (JST 1mm, 4-pin)\n\n\nIdeal For\n\nUsing multiple identical Qwiic sensors on one bus\nExpanding I2C address space\nMulti-sensor projects with address conflicts\nLarge-scale I2C sensor networks\n\n\nPackage Contents\n\n1× SparkFun Qwiic Mux Breakout – 8 Channel (TCA9548A)\n","vendor":"SparkFun","product_type":"physical","in_stock":false,"options":[],"variants":[{"id":4195,"title":"Default Title","sku":"SF-BOB-16784","price":29.48,"on_sale":false,"in_stock":false,"available_quantity":0,"option1":"Default Title"}]}
