Overview

The Seeed Studio XIAO nRF52840 Sense is an ultra-small development board powered by the Nordic nRF52840 SoC, featuring Bluetooth 5.0 and multiprotocol support. This 'Sense' variant includes an integrated 6-axis IMU and a pulse-density modulation (PDM) microphone, making it a capable platform for tinyML and wearable applications. The board comes with pre-soldered headers and features a thumb-sized form factor with a USB-C interface.

Why Choose This Part

The board offers a highly integrated sensor suite including an IMU and microphone within a tiny 21mm x 17.5mm surface-mount compatible package. It supports multiple wireless protocols including BLE, Zigbee, and Thread, and features an onboard battery charging chip for mobile power management.

Applications

Wearable Devices
Utilizes the onboard IMU and low-power Bluetooth 5.0 for activity tracking and gesture recognition in a compact footprint.
Edge AI and TinyML
Leverages the ARM Cortex-M4F processor and onboard microphone for voice recognition and vibration analysis at the edge.
Wireless HID
Acts as a compact Bluetooth Low Energy controller for wireless keyboards, mice, or custom macro pads.
Smart Home Sensors
Functions as a battery-powered Zigbee or BLE node for environmental monitoring and automated control.

Getting Started

Developers can program the board using the Arduino IDE by installing the Seeed nRF52 mbed-enabled boards package or utilize CircuitPython and MicroPython. For professional development, it is compatible with the Nordic nRF Connect SDK and Segger Embedded Studio. Connect via the USB-C port to flash firmware and use the onboard reset button for bootloader entry.
