Overview

The Seeed Studio XIAO nRF52840 Sense is an ultra-small form factor development board based on the Nordic nRF52840 SoC, featuring an ARM Cortex-M4F core running at 64MHz. This advanced version integrates a digital PDM microphone and a 6-axis IMU, making it a specialized platform for TinyML and motion-sensing applications. It provides 2MB of flash and 256KB of RAM while supporting Bluetooth 5.0 and NFC in a compact 17.5mm by 20mm package.

Why Choose This Part

The board offers a high-performance ARM Cortex-M4F with a floating-point unit and substantial 2MB flash memory, which is significantly higher than standard nRF52840 modules. Its integrated onboard sensors and battery charging circuitry reduce the need for external daughterboards in portable designs.

Applications

TinyML and Edge AI
Utilizing the onboard microphone and 6-axis IMU for voice recognition or gesture sensing via machine learning frameworks.
Wearable Devices
Leveraging the ultra-small footprint and Bluetooth 5.0 connectivity for compact fitness trackers or health monitors.
Battery-Powered IoT Sensors
Taking advantage of the low power consumption (under 5uA in standby) and integrated battery management for remote monitoring.
Wireless HID Controllers
Creating custom Bluetooth keyboards, mice, or game controllers using the 11 GPIOs and integrated BLE stack.
