The UNIT 8-Encoder is a set of 8 rotary encoders as one of the input units. It has an STM32 single-chip microcomputer as the acquisition and communication processor, and a host computer using an I2C communication interface. Each rotary encoder corresponds to 1 RGB LED light, there's a physical toggle switch and its corresponding RGB LED light, including a 5V->3V3 DCDC circuit. The unit can be used for the input of multi-channel relative control values, the corresponding RGB lamp can display different statuses, and the toggle switch can be used for the input of multi-channel switching quantities. It can be used as a multi-degree-of-freedom robot or a music equalization application.
