The Adafruit Terminal Block BFF Add-On transforms QT Py and Xiao boards with screw-terminal blocks on every pin, dual-socket headers for wire connections, and integrated Stemma QT connectivity. Features built-in LiPoly battery charging (250mA, adjustable to 500mA) with automatic USB power switching, plus support for standard AA battery packs. No soldering required for plug-and-play operation with pre-soldered headers. Stack-compatible design preserves all GPIO pins. Ideal for portable IoT projects, sensor integration, and rapid prototyping. Works with any QT Py or Xiao board—no code needed. Dimensions: 43.2mm × 30.3mm × 10.7mm.

When you were a kid, you may have learned about the \"buddy\" system; well, this product is kinda like that! A board that will watch your QT Py's back and give it more capabilities.\u003c\/p\u003e\n\u003cp\u003eUnlike most BFF's, this one has sockets for a QT Py to plug right into. If your board has headers already soldered on, you can plug and play.
