Understanding Flora, Gemma, and Circuit Playground

In this section, we will look at the exciting choices we have for creating wearable designs with circuit boards designed specifically for this purpose. Here, we will look at Adafruit Industries in New York, founded by Limor Fried in 2005 (Ladyada) and certified as A Minority and Woman-owned Business Enterprise (M/WBE). We will look at their sewable circuit boards, including Flora, Gemma, and Circuit Playground.

We’ll learn about the differences between these microcontroller boards. Then, we’ll explore a range of components that connect to our circuits to add interactivity. Finally, we will investigate other systems that you may want to learn about through your research.

We will cover the following topics:

• Adafruit Flora, Flora sensors, and snaps
• Gemma M0
• Circuit Playground Classic, Express, and Bluefruit
• Other toolkits

Let’s get started.
