Adafruit Qwiic / Stemma QT 5 Port Hub
32 units available with a short lead time.
The Adafruit Qwiic / STEMMA QT 5-Port Hub is a passive I2C splitter that lets you connect up to five STEMMA QT or Qwiic devices in a star topology instead of a long daisy chain. This reduces I2C line capacitance and gives you more flexibility in your mechanical layout.
The board has five vertical JST SH 1 mm connectors in a row, all sharing the same power, ground, SDA, and SCL lines. Breadboard breakout pins are included if you prefer wired connections. Mounting holes let you secure the hub to any enclosure or project, and a small power LED confirms connectivity.
Key Features
- 5 STEMMA QT / Qwiic Ports – Vertical JST SH connectors in a row
- Star Topology – Reduces I2C bus capacitance compared to long daisy chains
- Passive Hub – All ports share the same I2C bus (power, GND, SDA, SCL)
- Breadboard Breakout – Header pins included for breadboard prototyping
- Mounting Holes – Secure the hub to any project or enclosure
- Power LED – Visual confirmation of bus connectivity
- No Soldering Required – Plug and go with STEMMA QT / Qwiic cables
Ideal For
- Connecting multiple I2C sensors to a single bus
- Star-topology I2C layouts for reduced capacitance
- Projects where mechanical layout benefits from a central connection point
- Rapid prototyping with STEMMA QT / Qwiic accessories
