Small form-factor microcontroller board families

Which of the following board types / eco-systems do you think has the largest exposure and has been used in real projects the most?

 

This is about form factors smaller than the standard Arduino Uno format. I am thinking about new shields and want to put a second connector option on there to make it more flexible. It is going to be a display function, so I am not really interested in the higher power computer modules like RaspberryPi and such which already have video output.

  • I've been thinking about this too, and I've concluded that Adafruit's feather would be the way to go if ever I'm to settle on a form factor for myself.

     

    Adafruit (like Arduino) is investing a lot on their ecosystem and they have a shield-system in place as well (feather wings, in their parlance). They also are investing a lot on interconnects like their stemma and stemma qt connections, and have been updating their past breakout boards to be compatible.

     

    Nothing beats the Arduino Uno R3 shield eco system right now, but if I were a betting person I would bet on the feather form factor as the one that would take over for the "smaller size but still capable" segment.

     

    Nano would come in close, but I feel that's more for breadboard friendliness rather than expandability (you can't really stack expansions on top of the nano without much changes) and the pin count might be too small especially for microcontrollers like the nrf52840 which has 48 gpios.
