WildBay
Ultra-low power 2.4 GHz System-on-Module based on the STM32WB35 SoC, supporting Bluetooth 5.2, Thread, and Zigbee 3.0 for versatile short-range IoT connectivity.
Overview
The WildBay is a compact System-on-Module designed for ultra-low power 2.4 GHz wireless applications. Built around the STMicroelectronics STM32WB35 System-on-Chip, it integrates an ARM Cortex-M4 application processor and an ARM Cortex-M0+ network processor with a 2.4 GHz radio on a single die.
This architecture enables seamless multi-protocol wireless communication while maintaining the ultra-low power consumption that IoT edge devices demand.
Wireless Protocols
- Bluetooth 5.2 — Low Energy, long range, high throughput, advertising extensions
- IEEE 802.15.4-2011 — PHY and MAC layer support
- Thread — Mesh networking for IoT with IPv6
- Zigbee 3.0 — Industry-standard home and building automation
Key Features
- Dual-core STM32WB35 SoC (Cortex-M4 + Cortex-M0+)
- Ultra-low power consumption for battery-powered deployments
- Integrated 2.4 GHz radio transceiver
- Multi-protocol support on single hardware
