Sulivan22:
I'm trying to make the schematic with eagle but i am lost.. i dont know the element the i need for create the board...
Eagle files for the boards are listed with those boards on the hardware page of this site. Assuming your plan is to design a custom Arduino with ethernet and PIR then you can start from the Uno and start adding/moving/removing components.
yes, that is what i want.... i thinks is better the arduino ethernet and modify/remove or add the components that i need. but that is my problem.... here i am lost.. i dont know whats remove or how add.
Add the ATMega328; only requires a few components - uC, xtal, 2x 22pf caps, 4x 100nF caps, 10k resistor, small diode.
ICSP header pins for downloading bootloader if needed, USB/Serial header pins for down loading sketches, or adding USB connectivity out to a PC while debugging.
Basically the parts that make up a Promini with the 2 sets of header pins for programming.
If you've decided what crystal you are using, you can delete 2 of Q1, Q2, Q3.
Check the pinouts on J1 - looks like its set up to accept an FTDI Basic or similar - make sure Tx on whatever that device is goes to Rx on the '328.
The '328 you have shown is the leadless part. You will need to bring its Reset, SCK, MOSI, MISO, +5, GND out to a 6 pin header so you can download a bootloader (or a sketch with no bootloaded) into it.
You will not be using a crystal on the '328? I think you will have better results with high speed communications (such as SPI) if you use a 16 MHz crystal/22 pF caps with it. You can always not install it later, but it will be hard to add one if you don't have room for it at the start. You can use a small surface mount part if you want:
I think there's an existing library symbol for this part.
You have several signals that end in LED - where these intended to drive LEDs that show status or something?
When you think you're all set, run the eagle Design check (bottom left button on the left hand menu bar) to help identify things that look connected but may not be.
umm thanks this is a littler hard for me. i am using the same components that the Arduino Ethernet Board the crystal is the same and the J1 is the same FTDI Basic that the Ardu Eht board.
i want the power through POE... can i download the scketch through FTDI ?
attached the schematic eagle file and the arduino ethernet board eagle file too..
You can leave off the ethernet connection while downloading sketches via the FTDI port (J1).
If you are using an FTDI Basic, connect pin 2 to GND also.
Your J1 pinout looks good to mate with this after you connect pin2 - it is an input to the FTDI Basic.
I can't see the eagle files from here, will check at home.
