Arduino board in size DIP26 (33 x 10mm)

[avandalen]

I have developed a revolutionary tiny Arduino board: the Arduino DIP. It is an Arduino compatible board that is smaller than the ATmega328P-PU chip on the Arduino Uno itself. 
It has the same features as the Arduino Uno or Nano.

See for the circuit at my website: https://avdweb.nl/arduino/attiny3217/dily3217


Help wanted: Who has any ideas for improvement? Then I can include that in the design before making the PCB.
Who has  a better name for the board?

Here is the circuit:

not bashing your product / design 

you have the Adafruit ItsyBitsy M0    28 pins dip,  you win by 2,  but more powerful

Yes, I know, there are many Arduino boards which are more powerful. But not in this small size. The ATtiny3217 (and the STM32) is one of the best choices when PCB space is limited and a more powerful chip is not needed.

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.

How is it "revolutionary"?

[coromonadalix]

ok  you want US to help you in your commercial product is that it ?


mm not

Have you studied works of V.I. Lenin: "Prerequisites of the revolution"?

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.

I have also an USB port for programming on board.

You're right. I will try to make the board a little smaller. I can't use castellated pads because there are parts at the bottom side.

and what about the seeed xiao ? it's really smaller...

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 .

[coromonadalix]

yeah  same here

and still like other members don't understand  the "revolutionary"  thing ??  sound more like outdated,  small footprint but not practical  mcu wise

Yes, I know, the STM32 is more powerful and cheaper than the ATmega and ATiny. A nice little PCB too!

Having SDA and SCL on opposite sides seems... not ideal? Any thoughts on swapping 1(11) and 13(GND) so that they would be adjacent?
