Description

Powerful SoC with Advanced Connectivity & Security

Seeed Studio XIAO nRF54LM20A Sense is a compact, ultra-low-power wireless development board powered by Nordic Semiconductors nRF54LM20A SoC. It features a 128 MHz Arm Cortex-M33 processor, 512 KB RAM, 2 MB on-chip NVM, a 128 MHz RISC-V coprocessor, multiprotocol 2.4 GHz wireless connectivity, 8MB external flash, IPEX antenna connector, and Nordic nPM1300 PMIC for efficient power management.With support for Bluetooth LE, Bluetooth Channel Sounding, Bluetooth Mesh, Thread, Zigbee, Matter, and proprietary 2.4 GHz protocols up to 4 Mbps, this board is built for next-generation connected products. The onboard motion and audio sensors make it ideal for wearables, smart sensing, TinyML, gesture recognition, voice-triggered devices, and battery-powered IoT applications.Comprehensive security features include secure boot, secure firmware updates, secure storage, TrustZone-enabled trusted execution environment, cryptographic acceleration with side-channel protection, and tamper detection, ensuring robust protection for IoT deployments.

Ultra-Low Power Efficiency

Built on Nordic nRF54LM20A and nPM1300 PMIC, XIAO nRF54LM20A Sense achieves a measured deep sleep current of only 4.76 A under BAT power. Combined with the nPM1300 PMIC and its 0.33 A Ship Mode BAT current, in active wireless operation, it records an average current of 3.87 mA with a 3.7 V simulated battery input and TX power set to +8 dBm, the board is ideal for long-life battery-powered sensing applications, wearables, and always-on IoT devices.

Streamlined Development Experience

Full support for Nordic nRF Connect SDK and PlatformIO (Zephyr) enables efficient embedded development workflows.(Note: Arduino IDE is currently not supported.)
