Overview

The WBZ451PE-I is a multi-protocol wireless module based on a 64MHz Cortex-M4 CPU with a hardware Floating Point Unit (FPU). It integrates 1MB Flash and 128kB SRAM, supporting Bluetooth 5.2, Zigbee 3.0, and Thread 1.3.0 for robust 2.4GHz connectivity in a shielded 39-SMD package.

Why Choose This Part

This module simplifies design with an integrated PCB trace antenna and a hardware-based security accelerator for encrypted IoT communications. It offers extensive peripheral density including 29 GPIOs, 4 UARTs, 4 SPIs, and a 12-bit ADC, allowing it to function as a standalone system-on-module.

Applications

Smart Home Hubs

Serves as a multiprotocol gateway to bridge Zigbee and Thread sensors to a smartphone via Bluetooth.

Industrial Lighting Control

Leverages Zigbee Mesh networking and 22 PWM channels for sophisticated LED dimming and control.

Asset Tracking

Utilizes -103dBm sensitivity and 12dBm output power for reliable range in indoor environments.

Edge IoT Devices

The 64MHz ARM Cortex-M4 with DSP instructions handles local sensor data processing before transmission.
