We sell a handy TCA9584 expander breakout https://www.adafruit.com/product/2717 , its great for when you want to connect 8 devices of the same I2C address https://learn.adafruit.com/i2c-addresses but what if you want to do to it without any breadboarding – using Stemma QT or Qwiic? Someone emailed us about it, and we gotta admit, they’re kinda right. So here’s a design for a QTified version AND it has a level shifting/selector from Vin or 3.3V – which means that if you’re interfacing to 3.3V Qwiic boards from a 5V logic UNO, it will do the conversion for you – but if you want that 5V power passed through, you can do that as well.
