Yes! Stemma QT boards work with the Arduino UNO R4! 🎉🔌🛠️📡💡🌐
we just got our UNO R4 WiFi, featuring the Renesas RA4M1 series of chips https://blog.adafruit.com/2023/05/25/eye-on-npi-renesas-ra4m1-microcontroller-series-eyeonnpi-digikey-renesasglobal-digikey-adafruit/ an ESP32 wifi co-processor, an adorable LED grid, and a JST SH 4-pin connector…a.k.a a Qwiic port! Yay it is so great to see this connector becoming standardized on so many platforms. It means that all of our STEMMA QT devices https://www.adafruit.com/category/1018 will work plug-and-play. Here we're testing it with an OLED https://www.adafruit.com/product/938 and SHT41 breakout https://www.adafruit.com/search?q=sht4 we only had to update our demo to use Wire1 instead of Wire, since the secondary I2C bus is used for this connector. No soldering required!
