{"title":"Adafruit Qwiic / Stemma QT Breakout Board","handle":"adafruit-qwiic-stemma-qt-breakout-board","url":"/products/adafruit-qwiic-stemma-qt-breakout-board","description":"The Adafruit Qwiic / STEMMA QT Breakout Board bridges the gap between the STEMMA QT / Qwiic connector world and standard 0.1\" breadboard pins. One end has a JST SH-compatible connector for plug-and-play I2C, and the other has four 0.1\" spaced pads for soldering headers or wires to a breadboard.\n\nBuilt-in 10 K pull-up resistors on SDA and SCL keep your I2C bus tidy, and a green power LED confirms proper wiring. Use it with I2C controllers (Feather, Metro, QT Py) or I2C devices (sensors, OLEDs, GPIO expanders) — the lines pass straight through, so it works with both 3.3 V and 5 V logic.\n\nKey Features\n\n\nSTEMMA QT / Qwiic Connector – JST SH-compatible plug-and-play I2C port\n\n0.1\" Breakout Pads – Four pads (VCC, GND, SDA, SCL) for headers or wires\n\n10 K Pull-Up Resistors – On SDA and SCL lines (can be disabled by cutting traces on the back)\n\nPower LED – Green indicator confirms power and ground are connected\n\n3.3 V and 5 V Compatible – Passive pass-through works at either voltage level\n\nBidirectional – Use as a controller-side or device-side breakout\n\n\nIdeal For\n\nConnecting STEMMA QT / Qwiic devices to breadboards\nAdding a STEMMA QT port to boards without one\nPrototyping I2C circuits with standard 0.1\" headers\nQuick I2C bus debugging and testing\n","vendor":"Adafruit","product_type":"","in_stock":false,"options":[],"variants":[{"id":1029,"title":"Default Title","sku":"AF-5961","mpn":"ADA5961","price":3.86,"compare_at_price":0.0,"on_sale":false,"in_stock":false,"available_quantity":0,"option1":"Default Title"}]}
