One of these programmers is the JDM programmer, designed by Jens D Madsen. Please visit his website at www.jdm.homepage.dk and read all about the hardware and the associated software. On the right, you see his original design and the original circuit drawing. Among the members of the WISclub, the JDM programmer is a returning topic.. JDM Programmer Modification JDM Programmer Modification The JDM (or Ludipipo) seems to be among the most popular PIC programmers used - and rightly so: it is simple, cheap and easy to build, can be run with the free and excellent IC Prog software by Bonny Gijzen, and will program pretty much any PIC microcontroller on the market.

The article describes an updated JDM2-based PIC programmer schematic and layout that adds clock and data line filtering and a selectable Vpp voltage divider to support modern PICs (8-40 pin, e.g., PIC18F2455/4455).. Therefore, I improved Multi PIC Programmer 5V2 only a little at the end of last year. It is a circuit that can use a general purpose PNP transistor instead of a P-channel MOSFET.
