SparkFun Qwiic Mux Breakout – 8頻道 TCA9548A 多路復用器,多路轉換器,多路複用技術

你有太多具有相同I ² C地址的傳感器嗎？把它們放在 SparkFun Qwiic Mux Breakout上讓他們在同一輛公共汽車上交談！Qwiic Mux Breakout支持與多個I ² C設備通信，這些設備具有相同的地址，使其易於連接。Qwiic Mux還有8個可配置的地址，允許連接上最多64個I ² C總線。為了更方便地使用這個多路復用器，所有通信都是通過I ² C 專門製定的，利用我們便捷的Qwiic系統。

SparkFun Qwiic Mux Breakout 還允許您更改地址字節的最後三位，如果您需要在同一個I ² C端口上放置多個Qwiic Mux Breakout，則允許八個跳線可選地址。可以通過向三個ADR跳線中的任何一個添加焊料來更改地址。每個 SparkFun Qwiic Mux Breakout 均在1.65V至5.5V之間工作，非常適合我們內部生產的所有Qwiic板。

• 工作電壓：1.65V – 5.5V
• 工作溫度：-40 – 85°C
• I ² C地址：0x70（默認值），最大為0x77
• 9x Qwiic連接器

TCA9548A Qwiic Mux Breakout

Do you have too many sensors with the same I²C address? Put them on the SparkFun Qwiic Mux Breakout to get them all talking on the same bus! The Qwiic Mux Breakout enables communication with multiple I²C devices that have the same address that makes it simple to interface with. The Qwiic Mux also has eight configurable addresses of its own, allowing for up to 64 I²C buses on a connection. To make it even easier to use this multiplexer, all communication is enacted exclusively via I²C, utilizing our handy Qwiic system.

The Qwiic Mux also allows you to change the last three bits of the address byte, allowing for eight jumper selectable addresses if you happen to need to put more than one Qwiic Mux Breakout on the same I²C port. The address can be changed by adding solder to any of the three ADR jumpers. Each SparkFun Qwiic Mux Breakout operate between 1.65V and 5.5V making it ideal for all of the Qwiic boards we produce in house.
