Product details
Description
The Seeed Studio XIAO nRF52840 Sense is an ultra-small, high-performance development board engineered for modern Internet of Things (IoT) hardware and embedded Machine Learning applications. Powered by the Nordic Semiconductor nRF52840 ARM Cortex-M4 processor running up to 64 MHz, this thumb-sized microcontroller packs impressive processing power with a Floating Point Unit into a compact form factor. It is designed specifically for hardware developers, DIY electronics enthusiasts, mechanical keyboard builders, and engineers looking to deploy TinyML models in space-constrained environments.
This miniature board stands out due to its integrated advanced sensory hardware, featuring an onboard 6-axis Inertial Measurement Unit and a digital Pulse Density Modulation microphone. These features make it an exceptional tool for edge computing, voice recognition, and motion tracking projects without requiring external sensors. It supports ultra-low power consumption, drawing as little as 5 microamperes in deep sleep mode, and includes built-in lithium battery charge management to streamline portable power design. Compatible with popular open-source platforms like Arduino, MicroPython, and CircuitPython, this three-piece pack offers a versatile and scalable solution for creating custom wireless devices, wearable tech, and interactive prototypes.
How to use
