XIAO MG24 Sense - Matter-Ready MCU with Onboard IMU & Mic for TinyML & Advanced IoT
Unlock the future of smart connected devices with the XIAO MG24 Sense ! This ultra-compact development board is engineered around the powerful Silicon Labs EFR32MG24 SoC, bringing Matter-native connectivity (Thread & Bluetooth LE 5.3), exceptional RF performance, and advanced onboard sensors - including a 6-axis IMU and analog microphone - directly to your fingertips. It's the perfect choice for developers looking to build sophisticated TinyML applications, wearable technology, and responsive home automation solutions.
The XIAO MG24 Sense leverages the EFR32MG24's 32-bit 78 MHz ARM Cortex®-M33 core with DSP instruction, ensuring robust processing power for your projects. Its outstanding RF capabilities include an onboard antenna with up to 50m BLE range (in open, interference-free areas) and a UFL connector for an optional external antenna, making it ideal for wireless IoT projects . With a super-low power design consuming less than 1.95μA in sleep mode, it's perfect for battery-powered applications .
What truly sets the "Sense" version apart are its integrated analog microphone and 6-axis IMU (Inertial Measurement Unit) . These sensors open up a world of possibilities for edge AI applications , including pose perception, motion tracking, gesture recognition, and voice-activated controls. Security is paramount, with a dedicated hardware secure engine featuring Secure Vault functions. All this power and versatility is packed into the classic XIAO thumb-sized form factor, ensuring seamless integration with the vast XIAO accessory ecosystem.
