This ByteButton Unit is an 8-button touch input module with (you guessed it) 8 touch buttons and 9 colourful WS2812C RGB LEDs. It uses the STM32 microcontroller and communicates via I2C, letting you use this with a variety of different systems. The module includes two Port A connectors, allowing you to put multiple ByteButton Units together to create larger, more tricky setups. It has both button input detection and lighting feedback, making it great for projects such as smart home control, status displays and many more!
