Description

Development board Seeed Studio XIAO nRF54LM20A Sense is based on the Nordic Semiconductor nRF54LM20A, featuring a 128MHz Arm Cortex-M33 core and a 128MHz RISC-V coprocessor. The device provides 512KB RAM and 2MB of NVM, while the board additionally includes 8MB of external Flash memory. Power management and battery charging are handled by the Nordic nPM1300 PMIC.

Seeed Studio XIAO nRF54LM20A Sense - board dimensions

The compact XIAO form factor, measuring 21 × 17.8 × 4mm, makes the board suitable for portable devices and space-constrained projects. Wireless connectivity includes Bluetooth LE 6.0 with Channel Sounding, Bluetooth Mesh, Thread, Zigbee, Matter, NFC, Amazon Sidewalk and proprietary 2.4GHz protocols. An IPEX4 connector is provided for an external antenna. The board also features USB Type-C, a programmable RGB LED, a charging indicator and Reset and User buttons. It can be powered from 5V USB-C or a 3.7V lithium battery.

The Sense version additionally integrates an LSM6DS3TR-C 6-axis IMU, combining a 3-axis accelerometer and a 3-axis gyroscope, together with an MSM261DGT006 digital PDM MEMS microphone. The IMU supports interrupts and can be used to wake the system when motion is detected. The board is suitable for wearables, motion sensing, IoT systems, sound-responsive applications and low-power sensor processing projects.
