The Adafruit IoT Button with NeoPixel BFF adds a chunky 12 mm tactile button and an RGB NeoPixel to any QT Py or Xiao development board. It's a quick way to build simple IoT button projects with visual feedback — press the button to trigger an action, and use the NeoPixel to display status.
Designed as a "Best Friend Forever" board, the BFF mounts directly onto the back of your QT Py or Xiao. Solder it permanently or use pin and socket headers for a removable setup. The button and NeoPixel pins can be reassigned by cutting and re-wiring onboard jumpers.
