How to build PCB Board (Arduino PCB) for ATMEGA328P-AU?

Hi All,

I want to make Homemade Arduino Using ATMEGA328P-AU. But I am not been able to find the guidance anywhere on the internet. I am Getting Tutorials regarding the ATMEGA328P- PU.

Can Anyone Help me With these? If one of you have already made it can you please share your Gerber Files?

Can I use this: http://actrl.cz/blog/wp-content/uploads/nano_ch340_schematics-rev1.pdf
to Create My Board?

or this: https://www.instructables.com/id/DIY-Arduino-Nano-/

Thanks.

Sorry, but considering the availability and price of Arduino Nanos and Pro Minis, that really is a waste of time.

it's ok. My Purpose is somewhat demanding this so I can't neglect or ignore this.

Is the purpose confidential ?

Sounds like another college project with instructions that it must be done the hardest way possible.

srnet:

Yes, It's Confidential.

OK, I am validated. :grinning:

And my advice is confidential.

Will you take the information you are offered and claim it as your work?

The only place I know to purchase PCBs that are already designed is OshPark or perhaps here ExpressPCB

You might also find the folks in the forums for Eagle and Kicad might be able to help you out. Both are programs to design PCB's and someone may have already made something similar you can use as a starting point.

Regarding Confidentially. Its not an issue with me. I'm not providing anything that has any monetary value to be concerned about.

I hope I helped you get started.

The Gerbers for the original Arduino should be really easy to find... the Pro Mini flavour is based on the -AU version.

Sparkfun And adafruit both publish multiple open source designs based on that chip.

Hi All,
Does it have to be built on a PCB or can
it be on a solder-less bread board? There
is a DIY article in Nuts and Volts Magazine
(March 2015) on that project.

Huh? The -AU part is a TQFP Surface-mount part. Outside of mad soldering skills, that means it pretty much requires a PCB. Yes, you could get a breakout board for the chip itself and put the rest of the components on a solderless breadboard, but at that point the case for a full Arduino Mini or Nano is even stronger. And there might be Sockets for the TQFP package that would plug into a breadboard - but be prepared for sticker shock!
If you want to use a breadboard, stick to the DIP parts!

So where are the current limiting resistors?

No need, if you do it carefully: light the LEDs for a very limited time. Use a combination of time & internal resistance to stop stuff from breaking.

I've seen a tutorial doing just that when playing with a 4x7-segment display, I remember it was Sparkfun, worked quite well. Can't find it now :frowning:

Oooh, now you are going to upset people. Mike will not approve!

LOL I agree that it's not a generally recommended method :slight_smile:
