3.3 USB Connectivity using PKOB4

The WBZ450 Curiosity Board includes an integrated programmer and debugger MPLAB PICkit On-Board 4 (PKOB4), which is a new generation of In-Circuit Debugger that requires no additional programming/debugging tool to get started.

The following are the features and capabilities of PKOB4:
  • Connects to computer through high-speed USB 2.0 (480 Mbits/s) cable
  • Programs devices using MPLAB X IDE or MPLAB IPE
  • Supports multiple hardware and software breakpoints, stopwatch and source code file debugging
  • Debugs your application in real time
  • Sets breakpoints based on internal events
  • Monitors internal file registers
  • Debugs at full speed
  • Configures pin drivers
  • Field-upgradeable through an MPLAB X IDE firmware download
  • Indicates debugger status through on-board LEDs development board functionality and features
  • Virtual COM port (VCOM)

PKOB4 on the WBZ450 Curiosity Board is intended to support programming and debugging the target device, WBZ450PE Module through the Micro-B USB Connector (PS) (J7) from the host PC and to act as a USB to UART converter using PICKIT4 On-board virtual COM port.
