Hallo..i want to have schematic USB PIC Programmer, can any body help me??because i make a PIC programmer JDM2 using serial port DB9, but this programmer can't using Laptop to download it, much using PC Dektop to use it. So, i want to make other Programmer for use it with Laptop
Have a look at the PicKit2 on Microchip.
It is very cheap.
You can find schematics, firmware and software, source code for the whole thing on Microchip.
Unless you're really attached to the idea of assembling a kit, I'd choose the PICkit 2. You can get the fully assembled/tested unit directly from Microchip's website for under $40 (not including shipping).
I was wondering if the programmer layout in the link you've provided has under board jumpers? The BRD file is Different from the PCB layout given in the PDF file. Can you just confirm this or is the late hours really getting to me? If possible can you also provide a component overlay for the PCB given?
thanks

P.S. Sorry for Digging up a really old post but I was quite in a urgent need to have a PCB design ASAP. Thanks!
I dont remember about jumpers. Coz i had it in my collection and was saved from some uploads. The said PCB was designed for the given schematic. (Pickit2 lite from Blueroom) You may trace the PCB or start assembling as per the schematic and you'll naturally find where you need jumpers. The layout shown is solder side layout.
Cheers
