• Powerful SoC with Advanced Connectivity & Security

XIAO nRF54L15 (Pre-Soldered) 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 (Pre-Soldered) 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.

• 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)

• Solder-Free for Instant Creation

The pre-soldered headers mean you can start creating immediately – just unbox and plug into your breadboard. No soldering iron, no waiting, no hassle. Perfect for rapid prototyping, educational workshops, beginner-friendly projects, and time-sensitive development. Because great ideas shouldn’t wait for solder to cool.
