Unpopulated UNO R3 board?

Hi all,

I am wondering if an Arduino UNO R3 [u]BARE UNPOPULATED BOARD[/u] is sold by someone?

I don't want a proto-shield... I want an UNO R3 without any parts on it.

Anyone know if and/or where I can find this?

Thanks!

Perhaps the iTead Studios bare Duemilanove, MEGA 1280, or Nano 3.0 boards would be close enough?

The DangerousPrototypes forum says that they had bare UNO boards but the link seems to be broken now: http://iteadstudio.com/store/index.php?main_page=product_info&cPath=19_21&products_id=276

Thank you!

Actually that board is even better because it has a thru-hole crystal rather than an SMT resonator.

What I want to make is an AVRISP. I already made one with a proto-shield and a ZIF socket, but using a bare Arduino board with simply the reset pin moved will be a much neater package (no ugly wires all over the place).

Thanks again... that's exactly what I needed!

(edit to add):

I did some measurements to see if a ZIF socket would fit and it seems as though it will:

Of course, I don't need any components other than the crystal and two little capacitors (both of which are well outside the socket footprint).

Thanks again for the link!

Update to this topic:

I (finally) received the Duemilanove boards I ordered (came on a slow boat from China - literally) :)

I had already purchased a Sparkfun ISP board, so I didn't need to build my own (THEN I bought an Atmel AVRISP MKII) so I don't need the Sparkfun board either so......

I installed a bare minimum of parts on a board (28 pin socket, 16 mhz resonator, 10K reset pullup and a 6 pin ISP header).

Now I have a VERY inexpensive and Uno compatible generic microcontroller that I can use for student projects!

Problem is right now ITead is sold out of those boards (and I only ordered 5 of them) :(

Hopefully they will have more sometime soon......

If all you need is the crystal and ISP connector, perhaps the EMSL business card would work as well: http://www.evilmadscientist.com/2008/tiny-portable-avr-projects-business-card-breakout-boards/

That's great! That's exactly what I need. Just a board to hold a 328P and crystal or resonator and an ISP connector. We'll develop the code on an Arduino board then burn the finished product to the "bare board".

Thanks!

The are Runtime board from nkcelectronics may suit your needs also http://store.nkcelectronics.com/arduino-runtime-board-rev-b.html

With the ICSP header, you can burn the sketch right to the board too with your MKii.

That's a nice board. I kinda liked the unpopulated Duemilanove boards that ITEAD Studio sold, but it seems they don't have them anymore.

I bought one of the "Evil Mad Scientist" boards and it's made well, but it's THIN! It's like cardboard... it bends easily and I'm not sure if it would hold up to hacking and other abuse.

I also wish that the Arduino "official" boards could be purchased without the headers (since I remove them for almost every project).

Oh well... thanks for the info!

The Leonardo and Pro are available without headers.

If you are using a lot of boards, you could come up with your own design with whatever customizations you'd like - see a lot of examples here www.crossroadsfencing.com/BobuinoRev17

Given the fact it's all open source hardware, couldn't you etch your own boards and follow one of the how to on the net to put together what you need?

Here is what mine looks like using a TinyUSB programmer. The Tiny programmer is able to supply +5vdc power for the carrier board so it's a nice self contained package.
