Description
XIAO MG24 is an ultra-low-power wireless development board based on Silicon Labs' EFR32MG24 SoC, featuring a high-performance 78MHz ARM Cortex®-M33 core. It‘s Matter® native over Thread® and Bluetooth® Low Energy 5.3, all supported by the Arduino® Core. With 4MB Flash onboard, 19 GPIOs, LED, and charging circuit, it boasts extremely low operating current and ultra-low-power modes, making it an ideal choice for IoT applications, especially battery-powered projects utilizing Matter® protocols.
- 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
- 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.
- (MG24 Sense) 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.
- (MG24 Sense) Security Encrypted On-Chip: A dedicated hardware secure engine containing its own CPU enables the Secure Vault functions.
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.
