An extended Qwiic shield that adds four Qwiic connectors to Teensy 4.1, Teensy 3.6, and Teensy 3.5 boards. Connects the I²C bus (GND, 3.3 V, SDA, SCL) to two horizontal and two vertical Qwiic ports for easy daisy-chaining of I²C sensors and actuators.
Includes a PROG button that mirrors the Teensy's built-in programming button, so you can trigger programming mode from either the shield or the Teensy itself. Headers are included but require soldering.
Key Features
- 4 Qwiic Connectors – 2 horizontal + 2 vertical JST connectors for I²C devices
- Extended Footprint – Sized for Teensy 4.1, 3.6, and 3.5
- PROG Button – Electrically parallel with the Teensy's programming button
- Daisy-Chainable – Connect multiple Qwiic devices (unique addresses required)
- Headers Included – 2× 24-pin and 1× 5-pin headers (soldering required)
Ideal For
- Adding I²C sensors to Teensy projects
- Rapid prototyping with the Qwiic ecosystem
- Audio and high-performance Teensy 4.1 builds
- Multi-sensor data acquisition

Resources
Jargon buster
Plain-language definitions for the technical terms used above.
- GND
- GND is the ground or reference connection (0 V) for a circuit. When connecting two devices together, their grounds must be joined so both agree on what counts as a low or high signal.
- Headers
- Rows of connector contacts on a fixed pitch (commonly 2.54 mm) used to link a board to a breadboard, jumper wires, or another board. They come as male pin headers and female socket headers; when a module ships with pre-soldered headers it can be used straight away, whereas bare pads require soldering the pins yourself.
- Qwiic
- Qwiic is a plug-in connector system for I2C devices that uses small 4-pin cables, so you can connect compatible sensors without soldering. It matters because your controller or adapter also needs Qwiic, or you will need a cable or breakout to wire it up.
- Shield
- An add-on board that plugs into a main controller board to give it extra features such as sensing, motor control or communication. Knowing a product supports shields helps you judge whether it can connect neatly into an existing maker-board setup.
