as long as I run 5v+, GND, RX, TX to my chip.. Im good.. I can then use/tap the DTR pad from the bottom of the board to use on the DTR of the circuit Im uploading my sketch to....right?
a shame it was brought out on top like the other pins.
xl97:
you dont have to use the 6-pin header do you?
Nope. You can wire it up any way you choose. I do use 6pin headers simply to keep with the standard FTDI pinout.
Note the included (very short) cable actually only has 5pins (you can see that in the picture that Lefty posted).
I mean treat this like any other FTDI cable..yes?
Sure, just get a couple of the 6pin female crimp housings (such as http://www.pololu.com/catalog/product/1905), remove the single pin plastic housing on each pin, and insert the pins in the correct order. Or use whatever size header you want, as long as it matches your board.
I'd suggest testing the pinout first just in case

You don't really need to pass 5v, but you've got the idea. I was going to post a picture of a modified board but there isn't much to show - simply a cut trace and a jumper wire. Takes 2 minutes and seems to work great.
Thank you very much, you are really kind! it would take ages for me to draw all the connections...I do quite well for a beginner in the schematic editor, but in the board editor I get into trouble :)..
Well I'd like it to be single sided (I think I've already mentioned that :D) and with a dip package atmega and other parts also normal size (let say 3mm leds) not smd size ..
Also maybe I'd like a led on D13 so I can diagnose if the arduino is properly working with blink sketch (or which pin is it, I know I have a led that blinks on my nano if I upload the sketch on it, its permanently on the board).
Oh another thing, I'd like it to be drawn in Eagle :).
I have another question about the bootloader,..I shouldn't buy atmega with optiboot (or uno bootloader) right, but instead with duemilanove bootloader right?

Physical chip pin 19 is the arduino digital pin 13. Just wire a resistor and led in series from that pin to ground, with the led cathode lead wired to ground. A 1K resistor is used in the standard arduino board.
Already designed - just needs a little tweaking.
Unfortunately only so many hours in a day, and I don't always get back to a thread I might be interested in (right away).
Yep that won't be a problem...I see its double sided right? :), I'll have to learn the correct technique to line all the lines right :)..
The board in your previous post isn't the same like in your last post right?
Yes, double sided.
I let eagle auto-route it. It does okay if you have good parts placement to begin with.
The design is almost the same, added a couple of caps to the +5 line, diode in parallel with the reset pullup resistor, the 3mm LED and current limit resistor, and put all the pins in one row to be breadboard friendly (assuming one installs right angle male header there).
Several folks have asked - here are the eagle files for the single-sided board I posted earlier.
Remember, I had not updated all the pin numbers, that was "left as an excercise for the reader".
Others had asked about a single-sided version. I'll post one of those in the next message.
