Boards Guide
You might think of the Gemma as a โliteโ version of the Flora. It has just 3 digital I/O pads, but at 1.1″ in diameter, itโs incredibly tiny. Like the Flora, it has an onboard battery connector, and is programmable via the Arduino IDE. While it may seem that its minimal I/O count limits its potential, many projects donโt require lots of I/O pins, making the Adafruit Gemma the ideal choice for simple wearables designs.
The Gemma is perfect for simple wearables projects. ย It is a great entry level board to get you started in the world of wearables.
