Picture of Arduino Project Board
The Arduino Project Board is basically a board to transer your ATMEGA168/328 to when you have completed your project and no longer need to use the Arduino as a development board. Simply transfer the programmed chip from the Arduino board to the Arduino project board and you are in business. Now your Arduino is no longer tied up in your finished project and you have a simple breakout board to work with independently of the Arduino.

Here are some basic instructions for assembling it and getting started.

Step 1: Go get stuff:

The complete Arduino Project Board Kit includes:

(x1) Arduino Project Board PCB (or you can make your own with ProjectBoard.pcb)
(x1) Bootloaded ATMEGA328 chip
(x1) 28-pin socket
(x1) 16 mhz crystal
(x2) 22pF capacitors
(x1) 0.1uF, 25V capacitor
(x1) 10uF - 47uF, 25V capacitor
(x1) 1K, 1/4 watt resistor
(x1) tactile switch
(x1) 7805 regulator
(x1) 9V battery clip

thats a very noisy circuit why are we limited to basics?

where can we buy it ?

Will Serial Communication i.e. Tx and Rx pins be working with this please?

Irock1483 years ago
hi ifim going to do this, i would also like to know where to get extra chips for arduino uno
I found about this instructable at the following kit's description/details on another webpage. Might as well return the favor, so here it is, all for $9.99 + shipping without the chip (and $11.99 with the chip):

It's out of stock, but these are Atmega328 chips loaded with the Arduino Uno bootloader

Your pin designations are off by one probably caused by the omission of AREF on pin 21 which puts AVCC on pin 20. D8 as shown should be D9 etc. This is an old post so I'm sure you caught this already but I'm looking to replicate this board and it wasn't quite right for my ATmege328P. Am I missing something? Wouldn't be the first time here :)
randofo (author)  hankster422 years ago
D8 actually wraps around to the opposite side. I had some problem with pin placement and shifted things about a bit. There is not clear pin to pin alignment.
Thank you for the clarification. Do you know anyone who is making a PCB like this for purchase? I don't have the ability to make my own board and the only one I did find was $5 US, which is almost the cost of all the components to be installed on it.

$5 is pretty reasonable for a board of this type.

The link points to a invalid file: FT4WHPKGS5TYQOA.tmp
pcooper2 ewaldo3 years ago
Yeah, and the write-up doesn't even mention what application opens a ".pcb" file, even if the uploaded ProjectBoard.pcb file were valid. It could be any of half-a-dozen freeware design programs, none of which are compatible. I tried PCB Designer in Ubuntu Linux. It didn't puke, but it also didn't display a layout.

also can anybody tell me if this is a double layer board or single layer??
i am new to all this and i am going to order pcb from a manufacturing company!!
akinich3 years ago
can anybody give me the size of this board
and if anybody doesnt mind making a gerber file or a eagle CAM
file and uploading
thanks in advance
+1 on the "where do you get the kit?" front... any UK distributors?
When I don't feel like making my own boards I have had very good experience with this seller on e-bay. One can buy boards as a kit or just the boards.


akinich arnefl3 years ago
does this work exactly like the board above???
if not wat are the differences????
thanks in advance

Hey, can anyone tell me how I can add a USB (or any other in-put method) to this board or make a separate bootloader "pc to chip".
I'd really appreciate the help, and thanks in advance!
To be honest the most easy way to program it is to have a separate programing setup, either an Arduino compatible board or build one on a breadboard.

I built this little guy just for programing these project boards. Easy to do because I had all the parts around. You could do the same thing on a breadboard if you have the parts.


I then use a FTDI cable to plug it into my computer.


Though the most easy method is buying an Arduino board for $15-20 and then moving the chip over to one of these project boards once you have your program all worked out.
The author recommended that someone add a status LED onto the board, as well as widen the holes a bit.

If someone has the "know how" you could probably add a resistor behind the 5V regulator and then an LED on the far left of the board.

Anyone up for the challenge?
Here is a double sided with wider holes an a red LED with a 120 Ohms resistor
You rock. I'm going to get 100 of these made up. At bulk prices they're not too expensive per board. Use a bunch for personal and school projects, and sell the rest.

That is if anyone is interested.

Anybody in the UK interested in getting some of these brilliant boards made locally?
James JamesHardiman co uk
I have some quotes ... they work out at about £2.50 each (plus postage) if I can get enough interest to be able to order 100 boards.

I just costed this in the UK, sourcing components as cheaply as I could. Turns out it's a great idea, but not worth the effort. I will either go with Arduino mini pro (which is VERY small), or Ardweeny (and I'll buy a bunch next time in the US!)

I changed a little bit to make the PCB single sided - by putting the + and - on the left hand side
cbrink arnefl3 years ago
Arnefl -

Thanks, that is great. Is there any way you could post the gerber file?
arnefl cbrink3 years ago
I have the pcb file made by ExpressPCB (a free program) and have no idea how to post it here. I can only see the option to upload an image.

Aaahh found it :-)
cbrink arnefl3 years ago
Great work - now us people using the toner method can make these boards. Thanks!
typomaniac3 years ago
great! I would love to buy a kit or at least the pcb board. Do you plan to make some?
the boards cam be make and sell by the same website from the pcb program expresspcbDOTcom/ExpressPCBHtm/Specs.htm

Arduino community love this.
Thank you for your work !
What software can open the attached file: FT4WHPKGS5TYQOA.tmp ?
Gstv.Inc dgx3 years ago
try change the name extension FT4WHPKGS5TYQOA.tmp to FT4WHPKGS5TYQOA.pcb AND SAVE!!!
Rednecknerd3 years ago
This is all I have found.

dgx3 years ago
It works !

Thanks arnefl and FastEddie.

Like arnefl said, you can open or modify this file in ExpressPCB, a freely downloadable program found at


after first renaming the file from .tmp to .pcb. Note that Instructables renames and then adds the .tmp extension to every file uploaded, including the ProjectPCB.pcb that arnefl uploaded earlier. Hope this helps. Thanks, arnefl and especially the original author, randofo!
Instructables tends to list files with a random name.tmp. This is the software that serves the files.
Just save it as something like projectboard.pcb.
I don't know what program it is for since Eagle will not open it.
