Nordic Semiconductor - nRF54L15 DK
The nRF54L15 DK is Nordic Semiconductor's development kit for the nRF54L Series — the ultra-low-power wireless SoC family that follows the long-running nRF52 line. A single board covers all three devices in the series: the nRF54L15 is fitted to the kit, while the smaller nRF54L10 and nRF54L05 can be emulated, so one purchase lets you evaluate the whole family before committing to a part. The headline claim for the series is a substantial cut in radio current alongside roughly double the processing performance. As we will see below, the datasheet largely supports that — though not in every respect, and not in the way the marketing figures first suggest. Key Features The nRF54L15 pairs a 128 MHz Arm Cortex-M33 application core — with the full DSP instruction set and a memory protection unit — with a separate 128 MHz RISC-V coprocessor, which Nordic calls the VPR. The coprocessor handles peripheral and I/O work independently, letting the main core stay asleep rather than waking fo...
