JDM PIC Programmer

This project provides an open-source hardware design for a JDM-style programmer compatible with many PIC microcontrollers.
It uses a serial COM port (RS-232) for communication and supports high-voltage programming (VPP ≈ 12–14 V) via the ICSP interface.

Features

• Supports a wide range of PIC10F, PIC12F, PIC16F/C, and PIC18F series microcontrollers
• Powered directly from the RS-232 serial port
• Uses standard ICSP signals: VDD, VPP/MCLR, VSS, PGD, and PGC
• Simple through-hole (THT) design, easy to solder
• Can be used with IC-Prog, PICPgm, or PicProg on Windows and Linux
• Fully documented pinouts and programming table
• PCB available for purchase via PCBWay
