A QWIIC 2 IN 1 is an I²C splitter that allows you to connect two Qwiic-compatible devices to a single I²C port. It enables quick, solder-free expansion of sensors and modules using simple plug-and-play connections.
Pin Configuration
- GND : Common ground reference for power and signals
- SCL : I²C Serial Clock line used for communication timing
- SDA : I²C Serial Data line used for data transfer
- 3V3 : Provides regulated 3.3V power to connected Qwiic devices
Key Features
- Dual I²C output ports for expanding one I²C bus into two
- Plug-and-play JST-SH connectors (no soldering required)
- 3.3V compatible logic and power
- Compact design for clean prototyping setups
Applications
- Connecting multiple I²C sensors (IMU, temperature, light, etc.)
- Rapid prototyping with development boards like Glyph C3
- IoT and embedded system projects
- Educational and lab experimentation setups
⚠️ Precaution Note
- Ensure all connected devices operate at 3.3V logic (Glyph C3 is not 5V tolerant).
- Avoid connecting too many high-current devices on the 3V3 line.
- Check for duplicate I²C addresses (devices must have unique addresses).
- Keep cable length short to avoid I²C communication issues.
