Arduino Pro 328 - 5V/16MHz
sku: DEV-09219
Description: It's blue! It's skinny! It's the Arduino Pro! SparkFun's minimal design approach to Arduino. This is a 5V Arduino running the 16MHz bootloader (select 'Arduino Duemilanove w/ 328' within the Arduino software). The power switch was moved to the side of the board (good idea Limor!) to allow control when a shield is attached.Please note: The right-angle power switch is fragile. We're working on making the switch stronger. For now, please be gentle.
Arduino Pro does not come with connectors populated so that you can solder in any connector or wire with any orientation you need. We recommend first time Arduino users start with the Duemilanove. It's a great board that will get you up and running quickly. The Arduino Pro series is meant for advanced users that understand the limitations of system voltage (5V), lack of connectors, and USB off board.
We wanted Arduino Pro to be low profile. The DC power jack footprint is available, but not populated. We recommend running the board with a LiPo battery for better portability.
We really wanted to minimize the cost of an Arduino. The Arduino Pro is like the Arduino Duemilanove (same pin out) but to keep the cost low, we used all SMD components, made it two layer, etc. This board connects directly to the FTDI Basic Breakout board and supports auto-reset. The Arduino Pro also works with the FTDI cable but the FTDI cable does not bring out the DTR pin so the auto-reset feature will not work.

If you would like to tell us more, you can fill out our form if you need some psycho-suggestive questions. Go to the form.
I assume that the board is populated with a 5V regulator where the 3.3V regulator is present in the schematic, but it would be great to get that cleared up.
I'm adding a couple of these to my wish-list for my next order...
out of curiosity, what does the FIDUCIAL package's purpose, between TX and RX?
Unlike the 168 version I could not manage to read the flash. Perhaps the security bit was set?
I presumed it was my old kanda software was to blame. It doesn't know about 328s but usually I can find a similar part and get the kanda programmer to work.
So I ended up with around 6 different software packages including AVRdude. AVRdude was the only one with a 328 device listed but it didn't work with my kanda programmer or the SF parallel programmer.
So I bought a USB pocket programmer. This had issues too but ultimately I got it to run.
It would go through the program cycle but not verify.
Reading back the flash showed it was partly programmed but on average ever second page was blank (ff).
I went back to the kanda and found exactly the same thing. I tried extending the programming time but nothing helped.
Continued in part2.
In the end I grabbed a new pro-328, added ISP pins and tried it on the kanda.
This one programmed and verified first time and my program ran.
So it seems the orginal 328 is somehow faulty. I'm pretty sure the orginal bootloader was working so they obviously managed to programme it in the factory but they possibly didn't use ISP.

Now, all of that said, for troubleshooting purposes you may want to provide some details on your project and how you lost your boards, since these are designed for the momentary heat of a soldering iron, and operating temperatures in excess of ~60' would be difficult to achieve with the arduino board alone and correct voltage.
Stick with the pro mini if you can. I had to use this simply because I needed the AREF port which was omitted on the mini.
On a side note: this 5V board boots and programs fine with the 3.3V FTDI/USB connector.
