not bashing your product / design you have the Adafruit ItsyBitsy M0 28 pins dip, you win by 2, but more powerful
It is an Arduino compatible board that is smaller than the ATmega328P-PU chip on the Arduino Uno itself.
What’s the key advantage over, say, one of the DFrobot Beetle series? They’re a smidgen bigger, but they include the USB port for programming.https://www.dfrobot.com/product-1075.html

Nice unit - but I have a slight quibble:Technically its 0.1" wider and takes up a larger area - not really smaller but shorter... If you had a version with castellated pads on the edge you could get down to 7.5mm narrow to be truly smaller and surface-mountable.
Those atmega and atiny are ancient, why develop for them when there're so many M0/M0+ MCUs around?Way more powerful, while also cheaper.I would go with the STM32G030 ($0.35), or the py32f002A ($0.11), the py32 is crazy cheap and has Arduino support .
