Microcontrollers of the PIC series are connected to PICkit3 via the ICSP interface
PICKIT2 is a cheap development tool for PIC. Although it supports less ICs than KIT3ICD2, it is much better than K149 150 and its stability is better than ICD2. It can also be batch programmed offline.
Open the software, configure->select device PICKIT2 is supported by the green light.
KIT2 is a good choice for beginners.
PICkit3 is Microchip's online simulation and downloadable development tool designed for beginners to learn, evaluate, and develop PIC Series MCUs.
