Product description: Byte Button Unit - 8 button module + 9 WS2812C RGB diodes - Unit expansion module - M5Stack U192
Unit ByteButton is a compact module designed to detect inputs from 8 independent buttons . In addition to the buttons, the module is equipped with 9 WS2812C RGB diodes , which enable dynamic backlighting, serving as visual feedback to the user. Thanks to the STM32G031 microcontroller, the module provides efficient operation of buttons and LEDs, while offering simple communication with other devices via the I2C interface. The module can be used in various applications, such as control panels in Smart Home systems, interactive exhibitions, or educational devices. One of its key features is the ability to cascade, which allows for easy expansion of the system with additional units , e.g. increasing the number of buttons or RGB diodes in larger projects. It is compatible with popular programming platforms such as Arduino IDE and UiFlow , which makes its integration in various environments quick and easy.
