Nordic's nRF54L15 DK Three-in-One Dev Board Delivers Support for All Three nRF54L Wireless SoCs
Triple-threat board runs the top-end chip in the nRF54L line, but lets you lock down the SRAM and NVM to emulate cheaper models too.
Nordic Semiconductor has launched a development board built around its nRF54L15 wireless system on chip — with the ability to emulate the lower-cost nRF54L10 and nRF54L05 chips to provide a three-in-one platform for anyone targeting the company's nRF45L-series devices.
"The nRF54L15 DK is the development kit for all three wireless SoC (System-on-Chip) options in the nRF54L series," Nordic explains of its latest development board launch. "The nRF54L15 sits on the development board, while the nRF54L10 and nRF54L05 can be emulated. The affordable single-board development kit makes all features of the wireless SoC available to the developer."
The development board, brought to our attention by CNX Software, features Nordic's nRF45L15 at its heart, offering a single Arm Cortex-M33 processor core running at up to 128MHz with 256kB of static RAM (SRAM) and 1.5MB of non-volatile memory (NVM) plus a low-power RISC-V coprocessor core that Nordic uses to deliver "software-defined peripherals." The chip can then be configured to emulate the two lower-cost models in the nRF45L family, the nRF54L10 and nRF54L05 — both of which uses the same Cortex-M33 processor, but drop to 192kB of SRAM and 1MB of NVM or 96kB of SRAM and 512kB of NVM respectively.
As a wireless SoC, there's no surprise to find the nRF54L15 featuring an on-board radio module delivering Bluetooth 5.4 Low Energy (BLE) with direction-finding and Bluetooth mesh support, an IEEE 802.15.4 radio compatible with Zigbee, Thread, and Matter, Near-Field Communication (NFC) support, and the ability to handle proprietary 2.4GHz protocols with a data rate up to 4Mb/s. The development board brings out all the chip's general-purpose input/output (GPIO) pins, adds 8MB of SPI flash with quad-SPI support, two UART interfaces, SEGGER J-Link debug support, four user-programmable LEDs and matching buttons, a connector for direct radio-frequency (RF) measurement, and a USB Type-C port for data and power.
The Nordic nRF54L15 DK is now available in the channel for $39; additional details are available on the company's product page, alongside purchase links.
