ShrinkDuino UNO

Pocket sized ARDUINO UNO Clone

Similar projects worth following
My aim was shrinking the Arduino UNO to minimum size by simultaneously maintaining it's fundamental functionality and pinout.
The result is the ShrinkDuino UNO with ATMega328P and CH340G as USB-serial interface - well known from other Arduino UNO clones.
With a size of approximately 4.3 x 2.2 cm (without USB plug) it fits direktly to the USB port of a PC.

Major veto on the male pins vs female -- female jumpers are becoming a rarity and accidental shorts are more common.

What about connectorless USB PCB plug ?

May be it is an optical illusion, the connector spacing of the top two connectors in your picture does not look like they fall on a 0.1" grid to me.

You mean the gap between IO-pins 7 and 8? It's not 0.1" grid, but it's the same like on the Arduino UNO.

What is the advantage over Arduino Nano?

You can directly plug it into the USB-port :) And the pinout is the same like on Arduino UNO. That makes it easier to wire UNO shields to it. Admittedly a disadvantage are the missing LEDs for serial RxD and TxD.

I see. So from the practical point of view, I would need to get under my desk to plug it in, and I can't plug it into a breadboard because of the weird UNO half-pin header spacing.

Nobody said it's the perfect solution for everyone. But for some of my projects it's more practical than wiring an UNO by USB cable. Maybe it's because I don't use breadboards and I mainly use my notebook instead of a desktop computer.

It's always great to have more choice! Good luck with the project!

Hi, thanks for your hint. I just used this switch because I had it laying around in masses and it was very cheap.
