nRF54L15 DK: A Development Kit for nRF54L15, nRF54L10, and nRF54L05 SoCs with Bluetooth, Thread, and Zigbee

The nRF54L15 DK is a development kit designed to evaluate the wireless SoCs of the nRF54L15, nRF54L10, and nRF54L05 wireless SoCs. These SoCs support multiple wireless protocols, including Bluetooth Low Energy, Bluetooth Mesh, Matter, Thread, Zigbee, and 2.4GHz proprietary protocols, with data rates of up to 4Mbps. The kit integrates the nRF54L15 SoC and provides emulation capabilities for the nRF54L10 and nRF54L05, enabling flexible testing and development across the nRF54L Series.

The nRF54L series SoCs differ in memory configurations to meet various application requirements. The nRF54L15 includes 1.5 MB of non-volatile memory (NVM) and 256 KB of RAM for high-performance applications. The nRF54L10 features 1.0 MB of NVM and 192 KB of RAM for mid-range use cases, while the nRF54L05 offers 0.5 MB of NVM and 96 KB of RAM for entry-level designs requiring fewer resources. The kit is supported by the nRF Connect SDK and tools, providing access to software libraries and modules for exploring wireless communication and protocol integration in IoT, smart home, and industrial automation applications.
