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.

Some of your category choices seem confusing.

Firstly, the Sparkfun Qwiic does not really fit as a dev board form factor. It is a connection system for any dev boards. I see that Adafruit have adopted similar (also referred to as STEMMA QT) for most of their new breakout boards. E.g. https://www.adafruit.com/product/4646

SeeedStudio have the Grove connection system (similar to Adafruit's Stemma).

If that's what you are trying to understand (interface options) then you should have also include Mikroe's click form factor, which is commonly used.

Then secondly, the ESP 32/6288 category does not fit as these are modules. I don't believe there is an ESP32 dev board with the same pinout as the ESP8266 dev board unless it's in the feather form form factor. For ESP8266 there is the ESP-01, which is different to NodeMCU.

Good points, BigG.

I probably should ignore the Qwiic and ESP results, as they don't fit my intend at all. I will have a word with the person, who put them on the list.
