This XIAO MG24 is a small development board that uses the Silicon Labs EFR32MG24 SoC and the ARM Cortex-M33 processor. It supports Matter over Thread, Zigbee and Bluetooth LE 5.3, supported by the Arduino Core. It comes with 4MB of Flash, and is ideal for battery-powered home automation products due to its low power consumption (less than 1.95μA in sleep mode). There is an antenna attached to the board with a BLE range of up to 50m in an open location with no signal interference. A connector for an external uFL antenna can also be found on the board. If you're looking for the same dev board but with an analogue microphone and 6-axis IMU attached to it, click here to view it in our store. Now available in two options: board + loose headers, or a pre-soldered option. Please select an option before adding to cart.
