Icd2 Pickit2 Pic Kit 3 Programming Adapter Board Universal Programmer

$0

This adapter is not “configured” via software but rather through physical wiring. Here is how to set it up:

  1. Identify Your PIC Chip: Find the exact part number of your PIC microcontroller (e.g., PIC16F877A, PIC18F46K22, etc.).

  2. Locate the ICSP Pins: Consult the chip’s datasheet to find which physical pins are used for the five ICSP signals:

    • VPP/MCLR: Programming Voltage (Usually pin #1)

    • VDD: Positive Supply Voltage

    • VSS: Ground

    • PGC: Serial Programming Clock

    • PGD: Serial Programming Data

  3. Configure the ZMorph Socket: Using the pinout diagram that comes with the adapter (or a standard ZMorph chart found online), place jumper wires on the board to connect the ICSP header pins (from your programmer) to the specific socket pins that correspond to the target chip’s VPP, VDD, VSS, PGC, and PGD.

  4. Connect the Programmer: Plug your PICkit 3 (or other supported programmer) into the 6-pin ICSP header on the adapter board via a standard RJ-11 cable (for PICkit) or a ribbon cable.

  5. Insert the Chip: Carefully place the PIC chip into the configured ZIF socket and lock it in place.

  6. Power the Board:

    • Option A (Self-Powered): The board can often be powered directly from the programmer (via the VDD pin from the ICSP header). Ensure your programmer can supply enough current.

    • Option B (External Power): For chips requiring more power, provide an external regulated +5V (or the chip’s required voltage) to the VEXT and GND terminals on the board. You must ensure the external power supply’s ground (GND) is connected to the programmer’s ground.

  7. Program: Use Microchip’s MPLAB X IDE or the standalone software to program the chip as you normally would.

  • Universal Adapter: Allows using Microchip’s PICkit 2/3 or ICD2/3 programmers with modern, surface-mount (SMD) PIC microcontrollers.

  • Solves a Key Problem: Many newer PIC chips come in small SMD packages (like TSSOP, QFN, SSOP) without standard ICSP headers; this board provides a physical interface for them.

  • ZMorph Socket: Features a versatile “ZMorph” zero-insertion-force (ZIF) socket that can be manually configured with tiny jumpers to fit dozens of different PIC chip pinouts and packages.

  • In-Circuit Serial Programming (ICSP): Supports the standard ICSP protocol for programming and debugging PIC microcontrollers.

  • Basic Design: A simple, passive PCB board that routes signals from your programmer to the correct pins on the target chip. It requires an external programmer (like a PICkit 3) to function.

This universal programming adapter board acts as a crucial bridge between Microchip’s popular development programmers (such as the PICkit 2, PICkit 3, ICD2, or ICD3) and the vast array of modern surface-mount (SMD) PIC microcontrollers that are too small or difficult to solder onto a prototype board. The primary challenge with these tiny chips (in packages like TSSOP, QFN, SSOP, DFN, etc.) is physically connecting the programmer’s pins to the correct microcontroller pins for In-Circuit Serial Programming (ICSP). This adapter solves that by providing a stable, reliable connection point.

The heart of the board is a ZMorph-style socket, which is a configurable Zero Insertion Force (ZIF) socket. By placing small jumper wires or switches according to a provided pinout diagram, you can map the programmer’s five key ICSP signals (VPP/MCLR, VDD, VSS, PGD, PGC) to any pin on the socket, accommodating virtually any PIC microcontroller pinout. This eliminates the need to build a custom programming header for every new project or chip type, saving significant time and effort for developers, engineers, and serious hobbyists. It is a passive device, meaning it does not contain any active electronics; it simply routes signals from your external programmer to the target chip.

  • Extreme Versatility: Supports a wide range of PIC microcontrollers in various SMD packages (TSSOP, SOIC, SSOP, QFN, DFN, etc.) through its configurable ZIF socket.

  • Protects Your Chips: The ZIF socket allows you to insert and remove chips easily without bending pins.

  • Saves Time & Money: Eliminates the need to design and solder a custom programming adapter for every new SMD chip you use.

  • Universal Compatibility: Designed to work with the standard 6-pin ICSP interface of Microchip’s most common programmers (PICkit 2, PICkit 3, ICD2, ICD3).

  • Clear Labeling: The board is typically well-labeled with connection points for power, ground, and the ICSP data lines.

  • Essential for Development: An indispensable tool for anyone actively developing or prototyping with Microchip’s SMD PIC microcontrollers.
