I've used this board and really like how easy it is. It has some limitations, but overall the board is great.

One thing I dont like is that there doesn't seem to be any easy access to the part numbers for the components. I tried looking up the number printed on the oscillator but I can't find out. Reason for my wanting this is that my math says there should be a particular number of interrupts in a second but it's over by 360 oscillations per second.

Arduino uses a standard 16MHz crystal. The actual part could be from any supplier, but they all function the same - the ATmega will operate at 16MIPS. You'll need to setup your timer functions accordingly. The crystal will have +/-20ppm tolerance so that's (20ppm * 16mhz) ~320 oscillations in either direction, worst case.

Any chance you'll be stocking the Arduino Duemilanove at SFE any time in the near future? :)

We are now stocking the Duemilanove.

1. I need someone to help me with pronouncing all these funny names, Arduino boards have...

2. You could have definitely chosen another one of these boards for your pictures... The power adapter is a bit out of place in this one...

At the very bottom it has audio files that tell you how to pronounce it!

I ordered this board from you guys thinking i was going to receive the Duemilanove instead i received the decimilia. This was kind of a let down although the board will work with the application i have planned for it i was just hoping to have the board contained and not have to open it up to switch over to usb power.

thx

Sorry about that! We tried to time the pictures and description correctly as the new stock arrived. I'm glad you're able to get it working - the Diecimila is still a really good board.

I would really like to buy one of this usb boards, no idea what am i going to do in my vacations inside an electronic lab without one of this.
Any news about the existence of this board or any sugestion to buy the pro without FTDI cable-board?

Is there an advantage to using this board over the AtMega168 with the boot loader installed?

by

|   August  1, 2009 at 6:53 PM

well there totally different products really.

if im not mistaken, you can remove the ATmega from the arduino development board, so with that you can program a chip, then take it off the board and put it in a circuit that has the 16 Mhtz oscillator on it, and you can use it without the arduino board.

so if you want a compact project you could do that, or if you have a serial port on your computer you could program it through serial.

but i would buy the usb board and get extra ATmega chips seperatley instead of getting alot of boards. then you could use a small development board (the ones with a bunch of copper lined holes on them) and make your own arduinos, for a fraction of the cost of buying all those boards at 30 bucks a peice. instead you would pay about 6 bucks for the ATmega and oscilator

(please note, my board is still in the mail. i dont know if the chips are able to come out, or if you have to desolder. the picture looks like it comes out though.)

TheTrustedOne: Is there an advantage to using this board over the AtMega168 with the boot loader installed?

You wouldn't have to build all the stuff around de µC (e.g. FTDI-chip for USB, quartz, etc...)

by the way, when do you guys think that it will be availaible in stock again?

cheers!

It is come with ATMega168 or ATMega328?

by

|   March  4, 2009 at 5:21 PM

I would like to know this as well. The text indicates that it's a 328, but if you look closely at the pictures of the board the chip is a 168.

by

|   August  1, 2009 at 6:55 PM

i would think the text would have updated info.

by

|   September 21, 2009 at 4:08 PM

The text and physical pictures are up to date. We carry the latest boards with ATmega328 (instead of pictured 168). You can read the IC in those pictures?! Wow. Good eyes!

by

|   March  2, 2009 at 1:21 PM

While I was pleasantly surprised to receive my Duemilanove with an ATmega328 installed (double the memory capacity -- hooray!), I was less than pleasantly surprised to see the price drop by $5 less than a week after I bought it. :(

What is exactly included in the package? Only the board? Which USB cable should I buy ?

by

|   May 22, 2009 at 10:55 AM

I would guess the board only.

You will need a A to B USB cable which can be found here

I just got mine yesterday, so I can tell you it's just the unit in an anti-static bag. Have to bring your own cord. I have a whole box of them that I've been collecting over the years... can finally put one of them to use.

On another note one the headers is misaligned, not a problem now, but will be if I try to put a shield on it. Easy enough to fix, though.

by

|   July 25, 2009 at 3:33 PM

My headers were misaligned as well. I wasn't sure if that was normal.

by

|   August  1, 2009 at 6:58 PM

what exactly do you mean my misaligned? is it just bent inward/outward slightly? or is it actually like not soldered properly?

i ordered one, i just wanna make sure i wont have any probs when it gets here

by

|   September 21, 2009 at 4:09 PM

These folks are correct. WYSIWYG. Just the board with ATmega328 pre-loaded with bootloader. You'll need to pickup a USB A-to-B cable from somewhere (us!) and possibly a power supply (us!) if you need to power some high current items like a motor (us too!).

by

|   August  5, 2009 at 9:52 PM

i got mine today in the mail. i am very pleased, i have only had it for about 6 hours and it has worked perfectly. i followed the instructions on the arduino.cc website to install the usb serial drivers, and it worked. it came with the ATMEGA 328 like the discription said (i guess some people had problems with it)

no missing parts, no damaged headers.

the only unexpected thing was that its a bit smaller than i thought. but i never really thought about it much before.

great product, as i say, its only been 6 hours and i already love it.

Can someone tell me, is there a ZIF version of this board? Or does one break out the soldering iron if they want that. It's no big deal, as I currently use this:

http://evilmadscience.com/tinykitlist/74-atmegaxx8
(EMSL target board for atmega168/328)

to program avr chips, so one can prototype on the arduino and then blast the code out onto other atmega*s separately. Just curious though.

by

|   October 20, 2009 at 10:00 PM

How do I remove the chip ? Googling only tells me that I can do it , not how to. Sort of looks like it's soldered in ? Or maybe I'm just dumb ?

by

|   October 20, 2009 at 10:59 PM

Yeah , I got it out. Though bent a few pins in the process. And bent a couple putting it back in. You just have to pry it up. Might I suggest you guys start carrying an "IC remover" ? I've seen em on radio shack and it'd be really handy. Anyways you guys rock , thanks !

This board is awesome! I got the Duemilanove with ATMega328P processor. The bootloader makes it easy to upload programs to the board but it also has an ISP header if you want to program it using a normal AVR programmer. The Arduino software is a great beginner language and can also be used for a fair amount of advanced things since it is based around WinAVR's GCC C compiler. The large amount of software resources and libraries also simplify interfacing to many types of hardware. I got it driving a robot that used Vex Robotics motors from a serial input from my laptop the same day that I got it in the mail. Later I was able to interface it to an Xbox controller.

You can also use the Arduino as a programmer for other Arduinos or bare AVR chips (also to flash the bootloader onto a new chip) by running "Mega-ISP" on your Arduino and using avrdude to send the program through the Arduino to the target chip.

Hey I have a Question for all u smart people!..What is the best way to/built interface program between PC/Excel for Arduino USB Board.

Exsmaple: Take data from input to Excel Program or Axcess

Thanks!

Levi-
The Arduino connects to the PC as a serial connection, a usb serial port. It gets assigned a COM number like the other serial ports in the computer.

So what you need is software to connect a serial data source to excel, for instance. There are programs available to do this, but I cannot point you to any one in particular. There are serial data logging programs that store data in a format that can be imported into excel, for instance LabIML, which is free. But, if you are going to do that, you could do so using Processing pretty readily. So there are a variety of ways to proceed.

has anyone tried to replace the USB type B connector with a type A or a mini B connector. for me it is easier to find and use a mini B connector.
