Description

M5Stack Chain Angle is a compact rotary control module for the Chain ecosystem when you need accurate potentiometer knob input, clear device feedback, and easy serial expansion in a very small footprint. Built around the STM32G031G8U6 MCU, the M5Stack Chain Angle converts potentiometer knob input into digital data with up to 12-bit resolution, making the M5Stack Chain Angle a practical choice for human-machine interface panels, tuning consoles, and interactive embedded controls.

The combination of potentiometer knob input, RGB LED, and UART serial cascade protocol makes M5Stack Chain Angle especially useful whenever a rotary control module feels more natural than push buttons. For smart home control, audio knobs, parameter dials, and compact control surfaces, the M5Stack Chain Angle gives you stable potentiometer knob input inside a dependable human-machine interface design.
