Microchip WBZ451HPE Curiosity Development Board (EV79Y91A)

High-Power Multi-Protocol Wireless MCU Development Platform for Bluetooth® LE, Zigbee®, Thread, and Industrial IoT Applications

The WBZ451HPE Curiosity Board (EV79Y91A) is an integrated wireless development platform for evaluating the WBZ451HPE module. Its contain a high-power, multi-protocol 32-bit PIC32CX-BZ2 wireless MCU designed for Bluetooth® Low Energy, Zigbee®, Thread and 802.15.4-based application development. The platform is built around a 64 MHz Arm® Cortex®-M4F core and an ultra-low-power 2.4 GHz transceiver, supporting Bluetooth LE 5.2, Thread 1.3.0 and Zigbee 3.0 connectivity. Its +20 dBm transmit output supports longer-range and more robust wireless links for connected embedded systems.

For engineering bring-up, the board integrates PICkit™ On-Board 4 (PKOB4) programming and debugging, allowing power, programming and debug through a USB Type-C connection. Expansion is supported through a mikroBUS™ Click™ header and two Xplained PRO headers, enabling quick connection to add-on boards and access to GPIO resources for prototyping.

The board is preconfigured with an out-of-box Bluetooth LE sensor demonstration, while additional Bluetooth and Zigbee examples are available through MPLAB® Harmony v3 and Discover. This makes EV79Y91A suitable for engineers developing wireless lighting, industrial automation, home automation, IoT, Thread and proprietary wireless applications.
