The low-cost PICkit 4 in-circuit programming and debugging development tool is meant to replace the PICkit 3 programmer by offering five times faster programming, a wider voltage range (1.2 to 5 V), improved USB connectivity, and more debugging interface options. To address these needs and enhance the development experience, Microchip has introduced the MPLAB PICkit 4 in-circuit debugger. The debugging process remains an important area where many embedded-design engineers would like to see improvements, according to AspenCore’s 2017 Embedded Market Study, as cited by Microchip Technology.
