Description

Unit 8Encoder is an input unit that integrates 8 rotary encoders, using an STM32 microcontroller for data collection and communication processing, and communicates with the host via the I2C interface. Each rotary encoder corresponds to one RGB LED light. The encoder can rotate left and right and can also be pressed radially. Additionally, there is a physical toggle switch and its corresponding RGB LED light, and it contains a 5V->3V3 DC-DC circuit. This unit can be used for multi-channel relative control value input, with the corresponding RGB lights displaying different statuses. The toggle switch can be used for multi-channel switch input, suitable for applications such as multi-degree-of-freedom robots or music equalization.
