Feature(PICKit2 Programmer): PICKIT2 is a cheap development tool compatible with 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. KIT2 is a good choice compatible with beginners. ICs supported by PICKIT2 can be viewed with the MPLAB IDE software. Open the software, configure->select device PICKIT2 is supported by the green light. Feature(PICkit3 Programmer): PICkit3 is a development tool that can simulate and download PIC online. PICkit3 is Microchip's development tool compatible with online simulation and download designed compatible with beginners to learn, evaluate and develop PIC series MCUs. PIC Series Microcontrollers Connect to PICkit3 via ICSP Interface Supported Software: Direct support compatible with Microchip's official IDE (Integrated Development Environment Software) MPLAB Supported devices: Supports all PIC series microcontrollers with ICSP interface compatible with PICKIT3 supported ICs, you can view them through MPLAB IDE v8.92 Open the software, configure->select device PICKIT3 is supported by the green light.
