content: I have developed arevolutionarytiny 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/dily3217Help 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:

content: not bashing your product / designyou have the Adafruit ItsyBitsy M0 28 pins dip, you win by 2, but more powerful

content: Quote from: coromonadalix on February 12, 2024, 04:15:36 pmYes, 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.

content: Quote from: avandalen on February 12, 2024, 11:42:48 amNice 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.

content: Quote from: MarkT on February 12, 2024, 09:27:26 pmYou'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.

content: 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 theSTM32G030($0.35), or thepy32f002A($0.11), the py32 is crazy cheap and hasArduino support.

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 sound more like outdated, small footprint but not practical mcu wise

content: 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?
