Overview
When your modern Internet of Things (IoT) projects require robust dual-core wireless connectivity, low-power operation, and support for cutting-edge smart home protocols like Thread, Zigbee, and Matter, standard single-core microcontrollers fall short. The WeAct STM32WB55 Core Development Board provides an exceptionally affordable, high-performance wireless platform built around STMicroelectronics’ dual-core STM32WB55 microcontroller. Combining an ARM Cortex-M4 for application processing with an independent ARM Cortex-M0+ dedicated to real-time radio stacks, this development board delivers seamless Bluetooth LE 5.4 and IEEE 802.15.4 wireless communication for advanced maker and industrial prototypes.
Key Features
Advanced Dual-Core Architecture: Separate processing cores for application logic and radio stack management ensure rock-solid wireless performance without timing conflicts.
Comprehensive Wireless Protocols: Built-in support for Bluetooth Low Energy (BLE) 5.4, Zigbee, Thread, and Matter ecosystems.
Maker-Friendly Form Factor: Compact pinout layout complete with unsoldered header pins and debug breakout pads for flexible breadboard or custom carrier board integration.
USB-C Connectivity: Modern Type-C interface for power delivery and serial communication programming.
