The M5Stack Chain Buzzer combines audible alerts with a programmable RGB LED, with UART daisy-chain connectivity for easily linking it with other M5Stack Chain series devices.

The Chain Buzzer is a buzzer output node in the M5Stack Chain series.

It features a built-in buzzer and programmable RGB LED, making it suitable for audible notifications, status alerts, smart home alarms, and other applications. It integrates an STM32G031G8U6 core MCU and uses a UART serial daisy-chain communication protocol.

Two HY2.0-4P expansion ports allow additional Chain series devices to be connected, enabling richer audio-visual interactive applications.
