PIC18F2550 USB LED Matrix Board
NOTE: Please add yourself to our new maling-list. In there you will get exclusive information about this project, beta-testing, pre-releases and much more – http://elec.tkjweb.dk/matrix/
In March is designed a USB LED Matrix board which I afterwards got manufactured at BatchPCB.
USB Led Dot Matrix - Revision 1
After about a month I recieved the board, but unfortunately it had some manufacturing defects. I contacted BatchPCB and got a full refund.
You can read more about the defects in one of my other posts. But now I’ve fixed the defects using a razor blade and some wire.

Here is some assembly pictures…

Assembly step 6 - Finished
After a couple of hours programming I’m able to control the display using a nice GUI on the computer (made in Visual Basic 6). The programming is done in PicBasic Pro, and the flashing of the PIC18F2550 is easily done via USB, as I’ve installed Microchip’s PICDEM FS USB Bootloader on the chip.

hi.
I’m searching for the eagle library of this matrix. i tried to make one but got bad.
so. if you could say where you you get or put in the site for download I will be very glad.
thanks

Hi Raul.
I made a library myself with different parts used on this board.
The LED Matrix is one of the parts made from scratch!
