2.1 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 BLE, Zigbee RF Module WBZ351. This board offers integrated programming/debugging features using PICkit™ On-Board (PKOB4) debugger, and requires only a Micro-B USB cable to power-up and program the board. Users can expand its functionality through MikroElectronika mikroBUS™ Click™ adapter boards as well as Microchip's Xplained Pro (XPRO) header to interface with XPRO extension boards and do rapid prototyping utilizing the BLE, Zigbee enabled RF Module.

The WBZ351 Curiosity Board supports a variety of applications such as wireless lighting, home automation/Internet of Things (IoT), industrial automation and other BLE or Zigbee related applications.
