We wanted to try out the Arduino Portenta that has arrived, and what better way than to test it out with our STEMMA QT boards? There’s a 5 pin expansion port, which exposes the I2C pins and power+ground. Using our handy MKR to STEMMA cable https://www.adafruit.com/product/4483 we can plug in any of our 50+ sensors and displays. Here we show how adding an OLED and IMU is plug-n-play trivial and our examples just work!
