Introduction

This article describes various components of the Adafruit's Wearables, i.e. e-textile components.

According to Wikipedia (Aug 2019), “Adafruit Industries is an open-source hardware company based in New York City. It was founded by Limor Fried in 2005. The company designs, manufactures and sells a number of electronics products, electronics components, tools and accessories. It also produces a number of learning resources, including live and recorded videos related to electronics, technology, and programming.”

“In addition to our FLORA and GEMMA sewable microcontrollers, Adafruit's wearables category includes conductive textiles, battery packs, sensors and LEDs, and all-in-one packs perfect for beginners and as gifts.” (Wearables, retrieved August 28, 2019)

Adafruit wearables are an alternative to the Lilypad

Components of the Adafruit system

Below we provide a short overview. Our favorite system is the [Adafruit Circuit Playground Express]].

Microcontroller boards

All these boards, are some kind of tiny programmable computer and can connect to various other components, e.g. sensors, switches and LEDs.

659 FLORA V3

FLORA was until recently, Adafruit's main wearable electronics platform. It's built around the Arduino Atmega32u4 chip and has built-in USB support.

  • FLORA - Wearable electronic platform: Arduino-compatible - v3 (as of Aug 2019) is the main board. It it includes a processor, a LED and various connectors. ($ 15)
  • 4.4 grams
  • 4.5 cm diameter (1.75)
  • 7mm thick (0.3")
  • USB support (Micro B cable needed)
  • Battery connector (several battery types are supported, i.e. 3.5v to 16v))
  • 14 connectors / also used for sewing.

Circuit Playground

  • A FLORA board that integrates LEDs, made for learning Arduino programming.

Packs

Circuit Playground Express

Playground express are interesting for education since the board can be programmed with MakeCode, JavaScript or CircuitPython. In addition, it can communicate with other boards through the infrared sensor. In addition to the built-in LEDs and sensors, one also can attach external components.

Useful tools

At Adafruit

Making with Adafruit components may require various tools, some of which are not necessarily provided by Adafruit.

Local sellers

Compare prices before you buy. E.g. for once amazon.fr and Amazon.de offer very high prices.

Switzerland:

  • Playzone. Good choice.
  • Digikey (OK choice, good prices). Has threads.
  • Distrelec. Good choice. Good for institutional shopping. Delivers with bills. No threads.
  • Microspot Limited choice,
  • Amazon.fr and Amazon.de (limited choice, some very expensive)

Prices:

  • Adafruit part 641 (thread) varies from 7 CHF to 15,45 € (Digi-key vs. Amazon.fr)
  • Playtound Express: 25 CHF + TVA at Digitec, 38.28 € at Amazon.fr
  • Circuit Playground Express kit: 30.90 CHF + TVA at Digitec, 29.35 at Digi-Key.
  • Flora RGB Smart NeoPixel version 2 ($35) - Sheet of 20, 34.25 CHF at Digi-key
