M5Stack U186 Scroll Unit with Hollow Shaft Encoder

M5Stack U186 Scroll Unit with Hollow Shaft Encoder is a rotary encoder expansion in a scroll wheel. The M5Stack U186 features a 12-pulse through-shaft encoder, button input, and a WS2812C programmable RGB LED. The built-in STM32F030 microcontroller handles pulse signal acquisition, allowing users to read encoder values via I²C, simplifying operation. It is ideal for tasks like scale value control and volume adjustment.
