Overview

The STM32WB5MM-DK is a comprehensive Discovery Kit designed for evaluating the STM32WB5MMG module, which features a dual-core Arm Cortex-M4 and Cortex-M0+ architecture. It supports multi-protocol wireless connectivity including Bluetooth Low Energy 5.2, Zigbee 3.0, and Thread. The board integrates sensors and a display to facilitate rapid development of secure, low-power IoT applications.

Why Choose This Part

The platform simplifies RF design by using a fully certified module with an integrated antenna and built-in oscillator. The dual-core architecture separates application code on the Cortex-M4 from the wireless stack on the Cortex-M0+, ensuring real-time radio performance and enhanced IP protection. It provides 68 GPIOs and 256 KB RAM, offering significant headroom for complex multiprotocol firmware.

Applications

Smart Home Hubs
Building bridges between Bluetooth LE mobile devices and Zigbee or Thread mesh networks.
Industrial Sensor Nodes
Deploying wireless monitoring points that require 1024 KB Flash for complex local processing and dual-core security.
Asset Tracking
Utilizing the integrated antenna and small form factor module for compact, battery-powered tracking solutions.
Wearable Device Prototyping
Developing low-power devices that require a Cortex-M4 FPU for signal processing and a separate radio core.
