It features an onboard \u003cstrong\u003eBMI270 6-axis IMU\u003c\/strong\u003e, \u003cstrong\u003eLMD4020 digital microphone\u003c\/strong\u003e, and \u003cstrong\u003e500 mAh built-in lithium battery\u003c\/strong\u003e. Two HY2.0-4P expansion ports expose commonly used ADC, DAC, and UART peripheral pins for convenient connection to various sensor modules.\u003c\/p\u003e\n\u003cp\u003eThe base integrates 10 programmable SK6812 RGB LEDs on both sides. Combined with frosted light guides, they provide soft and even illumination. The bottom uses a Pogo Pin magnetic charging interface. When connected to a magnetic charging base, the onboard \u003cstrong\u003eTP4057 charging management IC\u003c\/strong\u003e safely and steadily charges the built-in battery. The Pogo Pin interface also exposes the host controller's \u003cstrong\u003eI2C bus\u003c\/strong\u003e, supporting magnetic external expansion. Built-in magnets and LEGO-compatible mounting holes on the back allow seamless integration with LEGO structures. \u003cstrong\u003eIt is suitable for IoT development, motion-sensing interaction, and
