3.1 Hardware

The WBZ351 Curiosity Board is a flexible and modular development platform that supports rapid prototyping and demonstrates the features, capabilities and interfaces of Microchip’s Bluetooth® Low Energy (Bluetooth® LE) and Zigbee® Radio Frequency (RF) Module WBZ351.

The WBZ351 Curiosity Board:
  • Offers integrated programming/debugging features using the PICkit On-board 4 (PKOB4) debugger interface.
  • Requires only a Micro USB cable to power-up and program the board.
  • Includes a mikroBUS Click header, which helps the users to expand the functionalities by connecting to various MikroElektronika mikroBUS Click adapter boards.
  • Microchip’s Xplained Pro (XPRO) header to interface with XPRO extension boards.
  • Performs rapid prototyping utilizing the Bluetooth Low Energy, Thread and Zigbee-enabled RF Module.
The WBZ351 Curiosity Board supports a variety of applications:
  • Wireless lighting
  • Home automation or Internet of Things (IoT)
  • Industrial automation
  • Other Bluetooth Low Energy or Zigbee-related applications
