The Seeed Studio XIAO MG24 Sense is a compact, ultra-low-power development board designed for advanced IoT and AI applications. Measuring just 21 x 17.8 mm, it integrates the Silicon Labs EFR32MG24 SoC , featuring a 78 MHz ARM Cortex-M33 core with DSP instructions and a floating-point unit, providing robust processing capabilities for complex tasks .

Feature

  • High Performance MCU: Silicon Labs' EFR32MG24 SoC , 32-bit 78 MHz ARM Cortex®-M33 with DSP instruction
  • Matter Native: Compatible with Matter® over Thread® and Bluetooth® Low Energy 5.3, Supported by the Arduino® Core
  • Outstanding RF Performance: Equipped with an on-board antenna with BLE range up to 50m in an open location with no signal interference, while reserving an interface for external UFL antenna
  • Super-Low Power Design: Power consumption less than 1.95μA in sleep mode, ideal for battery-powered home automation application
  • Advanced Onboard Sensors: Features additional analog microphone and 6-axis IMU for TinyML and edge AI applications such as pose perception for more responsive automation.
  • Security Encrypted On-Chip: A dedicated hardware secure engine containing its own CPU enables the Secure Vault functions.
  • Rich On-Board Resources: Additional 4MB Flash on board, on-board battery charging circuit, 19 GPIOs, LED
  • Classic XIAO Design: Remains the classic XIAO design of the thumb-size form factor of 21 x 17.8mm, and single-sided mount, making it perfect for space-limited projects such as wearables
  • XIAO Accessory Add-ons and Kits Compatibility: Natively compatible with all the XIAO accessory add-ons and kits of Grove Expansion, CAN-Bus, LED Matrix, Vision AI Sensor, Round Display, GSP Module, 2-Mic Array, ePaper Display, mmWave sensor, LoRa Module and many more.

Being the 12th member of the Seeed Studio XIAO family, the XIAO MG24 Sense remains the classic XIAO design (thumb-size, SMD, stamp holes). All these features make it a perfect fit for either space-limited applications of smart home, or a production-ready unit for your PCBA designs.
