Product description: Seeed Xiao nRF54L15 - BLE 6.0 / Thread / ZigBee / Matter / NFC - Seeedstudio 101991421
The Xiao nRF54L15 is a compact and advanced development board designed for modern IoT projects. It's based on the Nordic nRF54L15 , which combines a 128MHz Arm Cortex-M33 processor with a RISC-V coprocessor. With built-in power management, support for multiple wireless protocols, and industrial-grade security features , the board is ideal for wearables, smart sensors, and consumer products. Its compact size and USB Type-C connector allow for easy integration into commercial and hobbyist projects.
Seeed Xiao nRF54L15 - BLE 6.0 / Thread / ZigBee / Matter / NFC - Seeedstudio 101991421.
The development board supports multiple wireless protocols, including BLE 6.0, Matter, Thread, and ZigBee (IEEE 802.15.4-2020).

Communication pins and interfaces
The Xiao nRF54L15 module offers a wide range of connectors and interfaces – 16 GPIO pins support functions such as PWM, UART, SPI, I2C, and ADC. Additionally, there are JTAG/SWD debug pins for both the nRF54L15 chip and the supporting SAMD11 microcontroller. The board has two NFC pins and an IPEX antenna connector , which allows the use of an external antenna. The board also includes a user button, an LED, and a battery charge indicator . Wireless communication includes BLE 6.0. (including Channel Sounding), Thread, ZigBee, Matter and proprietary protocols 2.4 GHz up to 4 Mb/s.
Board pins.
Compatible with Amazon Sidewalk, Apple Find My and Google Find My Device via the nRF Connect SDK.
SDK programming and support
The Xiao nRF54L15 is designed with developers using advanced environments in mind. The board supports the nRF Connect SDK , the Zephyr RTOS operating system , and the PlatformIO environment. This enables the creation of stable, scalable applications using extensive documentation and ready-made code examples. It's worth noting that the module is not compatible with the Arduino IDE .
Differences between Xiao nRF54L15 and Sense version
The Xiao nRF54L15 Sense version has been enhanced with two key components: a PDM digital microphone and a 6-axis IMU sensor (LSM6DS3TR-C) . This enables projects based on sound analysis and motion detection. Compared to the standard Xiao nRF54L15 model, the Sense version offers identical performance, communication features, and pinout , but also expands application possibilities in areas such as wearables, HMIs, and gesture interfaces. Both versions are fully compatible with the nRF Connect SDK and Zephyr RTOS.
