Add a touch of sparkle to your wearables with the Adafruit Gemma Sequin Starter Pack. This beginner-friendly kit includes a GEMMA V2 sewable microcontroller, warm white LED sequins, conductive thread, needles, and a coin cell battery holder — everything you need to start sewing glowing electronics into garments and accessories.
The kit is designed for easy, no-soldering construction. Use the included conductive thread and needles to sew the LED sequins and GEMMA board directly onto fabric, then power the project with two CR2032 coin cell batteries (not included).
Key Features
- Beginner-Friendly – No soldering required, just sew with conductive thread
- Sewable Microcontroller – GEMMA V2 with alligator-clip compatible sew pads
- Warm White LED Sequins – Five tiny, bright, sewable LEDs for adding glow to any project
- Complete Sewing Kit – Includes conductive thread and a 20-piece needle set
- Battery-Powered – Coin cell holder with on/off switch for portable projects
Ideal For
- First-time wearable electronics projects
- Light-up clothing, costumes, and accessories
- E-textile workshops and STEM education
- Craft and maker projects with a tech twist
Package Contents
- 1× Adafruit GEMMA V2 – Miniature wearable electronic platform
- 5× Adafruit LED Sequins – Warm White
- 1× Stainless Thin Conductive Thread – 2-ply, 23 metre
- 1× Needle Set – 3/9 sizes, 20 needles
- 1× 2×2032 Coin Cell Battery Holder – 6V output with on/off switch
Resources
Jargon buster
Plain-language definitions for the technical terms used above.
- CircuitPython
- A beginner-friendly version of Python designed to run directly on microcontroller boards. If a product supports CircuitPython, you can often program it by copying code files onto the board rather than setting up a more complex toolchain.
- conductive thread
- Thread made with metal or other conductive fibres so it can carry electricity while being sewn into fabric. It matters for wearable and textile projects because it can replace wire, but it has more resistance than normal hookup wire.
- LED
- A light-emitting diode (LED) is a small electronic component that emits light when current flows through it in the correct direction. Because it only conducts one way, its polarity matters, and a through-hole LED must be soldered the correct way around to light up.
- microcontroller
- A microcontroller is a small computer on a single chip that runs a stored program and controls connected inputs and outputs such as buttons, sensors, displays and communication interfaces. In a device built around one, it is the part that executes the code and coordinates the device's behaviour.
- Motion detection
- The ability to sense that something has moved, either by comparing successive camera frames or by using a dedicated sensor such as a PIR (infrared) or radar module. When a product lists motion detection, movement can be used as a trigger so a system only acts or records when there is activity rather than running continuously.
- Thread
- A low-power wireless mesh networking standard designed for smart home and IoT devices. It matters because Thread devices can relay messages through each other, helping build reliable networks for sensors and controllers.
