- Powerful SoC with Advanced Connectivity & Security
XIAO nRF54L15 Sense is built on Nordic's nRF54L15 SoC with a 128 MHz Arm Cortex-M33 core (1.5 MB NVM) and dedicated RISC-V security coprocessor. This dev board supports multiple wireless protocols including BLE 6.0, Matter, Thread, and Zigbee (IEEE 802.15.4-2020). It also features new 4 Mbps mode for proprietary 2.4 GHz protocols. And it's compatible with major ecosystems like Amazon Sidewalk, Apple Find My, and Google Find My Device through nRF Connect SDK. Comprehensive security features include secure boot, secure firmware updates, secure storage, TrustZone-enabled trusted execution environment, cryptographic acceleration with side-channel protection, and tamper detection, ensuring robust protection for IoT deployments.
- Ultra-Low Power Efficiency
XIAO nRF54L15 Sense is optimized for long-life battery-powered applications, leveraging the Nordic nRF54L15 SoC's industry-leading efficiency (0.6uA in the chip's System OFF mode) and an integrated battery charging circuit. Final board-level power consumption data is currently being verified for accuracy and will be announced soon.
- Audio and Motion Sensing
XIAO nRF54L15 Sense integrates a high-quality digital microphone and a 6-axis IMU, making it ready for voice and motion-based projects out of the box.
- Streamlined Development Experience
Full support for Nordic nRF Connect SDK and PlatformIO (Zephyr) enables efficient embedded development workflows. (Note: Arduino IDE is not currently supported)
- Production-Ready Design with PCBA Support
XIAO nRF54L15 Sense features a production-optimized SMD (Surface Mount Device) design with standardized stamp holes, making it perfect for commercial PCBA (Printed Circuit Board Assembly) integration. Through our Fusion PCBA Sponsorship Program, you can not only enjoy the lowest unit prices for all XIAO modules from our Fusion Open Parts Library, but also fabricate and scale your XIAO-based PCBA designs at low cost (30% off) with FREE Design for Manufacturing consulting services, streamlining your journey from prototype to production.
