SparkFun Qwiic Mux Breakout - 8 Channel (TCA9548A)

by Sparkfun

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 the 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 operates between 1.65V and 5.5V making it ideal for all of the SparkFun Qwiic boards

The SparkFun Qwiic connect system is an ecosystem of I2C sensors, actuators, shields and cables that make prototyping faster and less prone to error. All Qwiic-enabled boards use a common 1mm pitch, 4-pin JST connector. This reduces the amount of required PCB space, and polarized connections mean you can’t hook it up wrong.

Features

  • Operating Voltage: 1.65V - 5.5V
  • Operating Temperature: -40 - 85° C
  • I2C Address: 0x70 (default) up to 0x77
  • 10x Qwiic Connectors
    • 2x Pass Through (Daisy Chain)
    • 8x Channels

The one-liner installer works well on a clean install of Retropie. The amp is just enough to drive a T1-2121SD

Upgraded my original Kickstarter Picade and needed this for Pi 4 compatibility. Works the charm- only wish is that audio was stereo. Other than that, it works well and was an easy upgrade! Recommended

Works perfect, very easy to setup, connecting all buttons, joystick and all has been as easy as it gets. Plus the on/off switch is a real treat compared to the old plug / unplug you're used to with the Raspberry Pi. Would recommend 100% !

This is a brilliant controller board for our arcade project, and makes it really easy to connect everything. We haven't tested it yet but it is a great board.

An excellent bit of kit! I paired it with RetroPie and my 1980s Competition Pro joystick to create my own little piece of 8-bit gaming heaven...

This is a great little board! I wanted to power a Pi and Pi Display in a SmartPi case with USB-C for a bit more power and this was available at an opportune time. The +/- are placed with just enough space to solder a right angle connector and feed wires through the case to the display. Still waiting to get hold of a PSU but this is working well off a bench supply. Software was easy to install, and the IO will come in handy for any controls I want to add to my project.

Bought this for an arcade project along with a Pi 3 A+. Easy way to provide on/off switch functionality, an audio amp with speaker output and any extra buttons needed.
