pickit 3 Description
Microchip’s PICkit3 In-Circuit Debugger/Programmer uses in-circuit debugging logic incorporated into each chip with Flash memory to provide a low-cost hardware debugger and programmer.
The MPLAB PICkit3 allows debugging and programming of PIC® and dsPIC® Flash microcontrollers at a most affordable price point using the powerful graphical user interface of the MPLAB Integrated Development Environment (IDE). The MPLAB PICkit3 is connected to the design engineer’s PC using a full speed USB interface and can be connected to the target via an Microchip debug (RJ-11) connector (compatible with MPLAB ICD 2, MPLAB ICD 3 and MPLAB REAL ICE). The connector uses two device I/O pins and the reset line to implement in-circuit debugging and In-Circuit Serial Programming™.

pickit 3 Basic Debugger System
The debugger system can be configured to use standard ICSP communication for both programming and debugging functions.
CAUTION: Do not change hardware connections while the PICkit3 or target is powered.
pickit 3 pinouts connection diagram
Connecting the PICkit3 to the target board through standard ICSP interface using 6-pin connector. The programmer connector pinout is shown in the figure below:
Be careful on the pin order while connecting.
Incorrect connection may damage the PICkit3 debugger/programmer or the target board.
PICkit3 Status LEDs
The Status LEDs indicate the status of the PICkit3.
- Power (green) – Power is supplied to the PICkit3 via the USB port.
- Active (blue) – The PICkit3 has connection to the PC USB port and the communication link is active.
Busy (yellow) – The PICkit3 is busy with a function in progress, such as programming.
Error (red) – The PICkit3 has encountered an error.
