Four days ago, I found out I needed to make a piece of a costume. The idea was to combine a TFT LCD with a microcontroller and Bluetooth Low Energy. I checked my microcontroller bin and found some Adafruit Feather Boards. In this post, I will introduce the feather family and provide a decision chart for choosing the right one for your project.
The Feather board have a standard footprint and pinout. Most(All?) have a USB connector, a microcontroller, two rows of pins, and a battery charger. They measure 50.80 by 22.86 mm, which is 2.0 by 0.9 inches.
