The Nordic Semiconductor nRF54LM20-DK is a wireless SoC development kit designed for engineers, embedded developers, researchers and students working on next-generation wireless applications. The kit features the nRF54LM20B wireless SoC and provides a practical platform for evaluating wireless connectivity, developing application firmware and exploring the capabilities of the nRF54L family.
The development kit supports multiprotocol wireless development, including Bluetooth Low Energy, 802.15.4, Matter, Thread, Zigbee, NFC and 2.4 GHz proprietary protocols. It includes integrated 2.4 GHz and NFC antennas, an SWF RF connector for direct RF measurements, and dedicated power-measurement pins for evaluating energy consumption.
For programming and debugging, the board includes a SEGGER J-Link OB programmer/debugger. Four user-programmable LEDs and four buttons support application testing and user-interface prototyping. The kit also provides 8 MB of external flash memory and two UART interfaces through virtual serial ports.
The nRF54LM20-DK is supported by Nordic Semiconductor’s nRF Connect SDK and development tools, making it suitable for embedded firmware development, wireless protocol evaluation, IoT prototyping, RF experimentation and educational projects.
