-
Powerful SoC with Advanced Connectivity & Security
- XIAO nRF54L15 is built on Nordic's nRF54L15 SoC with a 128 MHz Arm Cortex-M33 core (1.5 MB NVM) and a 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 a 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 is optimised 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.
-
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 features a production-optimised SMD (Surface Mount Device) design with standardised stamp holes, making it perfect for commercial PCBA (Printed Circuit Board Assembly) integration.
