Adafruit Feather/ItsyBitsy boards

Overview

Adafruit was founded in 2005 by MIT engineer, Limor “Ladyada” Fried. Her goal was to create the best place online for learning >electronics and making the best designed products for makers of all ages and skill levels.

Quoted from Adafruit website

Adafruit’s microcontroller boards are now spanning a wide range of features and Adafruit is well-known for their large number of high-quality tutorials on electronics, microcontrollers and IoT.

Listed boards

New to Arduino and microcontroller boards? Look at our tutorial on Arduino, Sensors, IoT and LoRa technologies and discover a whole world of embedded applications with microcontrollers.

Programming

Programming an Adafruit board can be realized from the Arduino IDE and most programs written for Arduino work on these boards.

Solution Lab: All Adafruit boards software packages are already installed in the Arduino IDE environment. Select the correct Adafruit board in the Tools/Board/Adafruit Boards menu section.

Usage

The listed Adafruit boards can be selected according to the IoT prototying profile, for instance:

  • Adafruit Feather M0 Lora: this board provides an ARM Cortex M0 core to test more resource demanding IoT applications. The embedded LoRa RFM95W module provides an introduction into LPWAN IoT connectivity. Look at the LoRa Communication section of our Arduino, Sensors, IoT and LoRa technologies. It has built in USB and 100mA lipoly charger with charging status indicator LED to quickly test various power management solutions.
  • Adafruit ItsyBitsy M0 express: the main features of the ItsyBitsy board is definitely its very compact form factor. In addition, the ItsyBitsy M0 express has the possibility to run CircuitPython code, opening perspective to the embedded Python world.
