AArduino ATmega328p extra mini board.

Description

Many other boards are huge.
Here is a very tiny arduino board.
After you'r polished the project enough, time to pack it.
Only 12.5mm X 25.5mm in size!
Can be flashed with arduino bootloader before or after soldering.

All pins are exposed on the back-board.
22 pads plus serial and additional power via 1.27mm pin header.

Version 0.9 is a complete version for now.
Unlit bug being found.
Free for privet use.

Looks cool and I can think of a few ways I'd use this. The pin labels on the back or ambiguous though--not obvious which label belongs to which pad.

Are you sure? yes | no

Sad to hear and thank you for feedback!!!

Ive added the last photo. Please take a look, that's why labels are looking strange.

When someone solder a pin header he'll see only half of labels.

There is another way to remember:

Clockwise from six while bottom view -> PWR, D2->D13, A0->A7, GND. That's all. Should be quite simple.

(Answer why board is so overloaded with routes and vias. lol that's why).

Thank you.
