Product description: Chain Buzzer - buzzer module with RGB diode - M5Stack U224
The M5Stack Chain Buzzer is an output node designed for creating acoustic and visual signals in projects using the M5Stack Chain ecosystem. The module incorporates an MLT-5020 buzzer and an addressable WS2812C RGB LED , allowing it to simultaneously generate audible signals and inform the user about the device's status via light. The device is operated by an STM32G031G8U6 microcontroller . Communication is via UART at 115,200 bps, and two HY2.0-4P ports allow for chaining with other Chain series devices. Its compact size makes the module ideal for alarms, operator panels, automation, and Smart Home systems.
Chain Buzzer - buzzer module with RGB diode - M5Stack U224.
Botland is an official distributor of the M5Stack module family in Poland. We have extended this system of stackable functional devices with accessories from our range and numerous blog guides. All M5Stack products presented here are original.
The ability to connect modules in the Chain bus facilitates the construction of more complex interactive systems.
