Building battery-powered, intelligent IoT devices used to require significant compromise: you either sacrificed processing power for battery life, or your board struggled to support modern wireless protocols like Matter and Thread without draining its power source.
Enter the Seeed Studio XIAO nRF54L15.
Built around the cutting-edge Nordic nRF54L15 SoC, this thumb-sized development board completely redefines what’s possible in edge computing. Upgrading from the legendary nRF52 series, the new nRF54L15 boasts a lightning-fast 128 MHz Arm Cortex-M33 core and an expanded 1.5 MB of non-volatile memory (NVM). This gives you the headroom to run complex code, manage multiple sensors, and handle heavy wireless traffic directly on the board.
Despite the raw power, it is shockingly efficient. Drawing just 0.6 µA in System OFF mode, this board is tailor-made for remote nodes and wearables that need to run for months-or even years-on a tiny battery.
Combined with native support for BLE 6.0, Matter, Thread, and Zigbee, and featuring built-in battery charging circuitry, it's the ultimate all-in-one wireless microcontroller for your next big project.
