مميزات خاصة
The Adafruit STEMMA QT / Qwiic PCA9548A Mux Breakout - 8 Channel has eight JST SH 1mm connectors in two rows of four, all with the power, ground, and SDA/SCL pins connected
There's one port at the end that connects to your I2C controller (there are also breadboard breakout pins if you need them)
Use this breakout to add as many I2C devices to the bus as you need. Complete with mounting holes so the board can be added to any system.
There's even an onboard 3.3V 500mA regulator, so if you're using this with a 5V microcontroler like an Arduino 328-compatible, you can level shift all the QT ports to have 3V power and logic level.
وصف
You just found the perfect I2C sensor, available in a handy chainable Qwiic, or STEMMA QT package, and you want to wire up two or three or more of them to your microcontroller when you realize "Uh oh, this chip has a fixed I2C address, and from what I know about I2C, you cannot have two devices with the same address on the same SDA/SCL pins!" Are you out of luck? You would be, if you didn't have this ultra-cool Adafruit PCA9548 8 Channel STEMMA QT / Qwiic I2C Multiplexer!
