11.1 USB Connector

The MPLAB PICkit 4 In-Circuit Debugger is connected to the host computer via a Micro-B USB connector, version 2.0 compliant. The Micro-B USB connector is located on the top of the debugger.

The system is capable of reloading the firmware via the USB interface.

System power is derived from the USB interface. The debugger is classified as a high power system per the USB specification, and requires slightly more than 50 mA of power from the USB to function in all operational modes (debugger/programmer).

Note: The MPLAB PICkit 4 In-Circuit Debugger is powered through its Micro-B USB connector. The target board is powered from its own supply. Alternatively, the debugger can power the target board only if the target consumes less than 50 mA.

Cable Length – The computer-to-debugger cable, shipped with the debugger kit, is the correct length for proper operation.

Powered Hubs – If you are going to use a USB hub, make sure it is self-powered. Also, USB ports on computer keyboards do not have enough power for the debugger to operate.

Computer Hibernate/Power-Down Modes – Disable the hibernate or other power saver modes on your computer to ensure proper USB communications with the debugger.
