The MPLAB PICkit 4 is a significant upgrade over the PICkit 3, offering faster programming speeds and expanded functionality without increasing the price. Powered by a high-performance 300MHz 32-bit SAME70 MCU, this debugger supports 8-bit to 32-bit devices. It supports advanced interfaces such as 4-wire JTAG and Serial Wire Debug (SWD) with a streaming Data Gateway, while maintaining backward compatibility with systems using 2-wire JTAG and ICSP.
Take your code into the field without needing a laptop. The PICkit 4 features a unique "Programmer-to-Go" function that lets you save project code to a micro SD card. Since the device can be powered directly by the target board, you can update firmware or debug in the field with minimal gear.
Connecting to your workflow is simple via a high-speed USB 2.0 interface to your computer and an 8-pin Single In-Line (SIL) connector to your target. The device leverages the powerful graphical interface of the MPLAB X Integrated Development Environment (IDE, v4.15+) to make debugging intuitive and efficient.
Whether you are upgrading from the PICkit 3 or equipping a new workbench, the MPLAB PICkit 4 offers the speed, portability, and versatility needed for modern embedded development. It combines the reliability Microchip is known for with the flexibility to work wherever your project takes you.

Note: If you have MPLAB X IDE installed, you can browse to the “docs” folder under your MPLAB X installation directory and open the file Device Support.htm to check for supported devices.
