M5Stack 8-Encoder Unit (STM32F030)
Product Link
Introduction
UNIT 8Encoder is a set of 8 rotary encoders as one of the input unit, the internal use of STM32 single-chip microcomputer as the acquisition and communication processor, and the host computer using I2C communication interface, each rotary encoder corresponds to 1 RGB LED light, encoder in addition to left and right rotation, but also radially pressed, in addition to a physical toggle switch and its corresponding RGB LED light, including 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 music equalization application.
