Prototype on 11u24 to PCB manufacture help
Hello guys , I 've been building a prototype for a while now based on LPC 11u24 and now that I have it working and the code has also been debugged I want to proceed and create a PCB based prototype that will show to my project markers how the final product will roughly look like . The problem is that the LPC 11u24 has extra bits and pieces that I dont need and because space is a very important parameter of my project I need schematics or even better eagle schematics of 11u24 . Also as I have never done this before I would like to ask for general guidance on how one can proceed from designing the pcb on eagle to finally soldering everything in . Another major issue is the way I ll transfer my program on the M0 itself . Is there any way I can keep the usb jack and drag n drop technique originally used in mbed . Please let me know , any help is appreciated. Thanks

While it won't tell you everything, a good place to start is the HDK: http://mbed.org/users/mbed_official/code/mbed-HDK/file/bc96cec5b238/NXP/LPC11U24-Lite (use the small button to download it as zip), and look at the LPC11u24. You are in luck regarding this one: It has its own integrated USB bootloader. So you can keep using the drag and drop technique without requiring extra ICs.
It might also help to look at other designs, for example the seeeduino has eagle files: http://www.seeedstudio.com/wiki/Seeeduino_Arch
Thanks for your post . A couple of things . Firstly the pins on the diagram do not correspond directly to the ones on the mbed , not even the ones next to PI.0x . Is there an easy way to find what I want or I have to go through them one by one and find the ones that interest me .And secondly you said that I will not use any other ICs to input my programs , is this covered in this design ? Or do I need to add components , as I see that this design is lighter version of my mbed . Thanks again for your time and support , have a nice day .

You can address those pins simply by instead of p10, using P0_4 for example. You can find the relation between mbed pins and LPC11u24 pins here: http://mbed.org/users/mbed_official/code/mbed-src/file/26fc69fd3b6c/targets/hal/TARGET_NXP/TARGET_LPC11UXX/TARGET_LPC11U24_401/PinNames.h.
