M5Stack 8Angle Unit is a compact potentiometer input module designed for analog adjustment, RGB feedback, and dense multi-knob interaction in embedded projects. This slim control bar works well as a multi-channel analog controller, an I2C potentiometer panel, and a flexible robot control adjustment unit for M5Stack, ESP32, and other maker platforms. Description M5Stack 8Angle Unit uses the STM32F030F4P6 to read eight potentiometer channels and publish the values over I2C. In daily use, this potentiometer input module gives us a simple way to adjust multiple parameters at once, while the RGB lighting and toggle switches add immediate visual and tactile feedback. That makes it a practical multi-channel analog controller for dashboards, parameter tuning, motion control, and interactive builds where several analog values need to stay within reach. Features M5Stack 8Angle Unit combines eight knobs, RGB indicators, and toggle interaction in one long-form control bar. Each knob contributes to a responsive potentiometer input module workflow for real-time parameter changes. The device behaves like a multi-channel analog controller for robotics, lighting, audio, and UI tuning tasks. Its Grove interface and I2C communication make it easy to deploy as an I2C potentiometer panel. Compact dimensions help when we need a clean robot control adjustment unit without building a custom front panel. Specifications Product M5Stack 8Angle Unit Type 8-channel potentiometer and RGB input bar Main MCU STM32F030F4P6 LDO ME6210A33M3G RGB Device SK6812-3535 Communication I2C Default Address 0x43 Input Voltage 5V Size 128 x 24 x 22.7mm Role Multi-channel analog controller / I2C potentiometer panel Applications M5Stack 8Angle Unit fits projects that need repeatable analog input without a large custom console. It works well in robotics tuning, servo adjustment, media control, parameter testing, stage props, education, and compact HMI builds. Because this potentiometer input module presents eight channels in a row, it is especially useful when we want one I2C potentiometer panel to manage brightness, speed, threshold, gain, timing, or angle values from a single surface. Product List 8Angle Unit x1 HY2.0-4P cable x1 Other Content This hardware is also a convenient robot control adjustment unit for drive systems, actuator testing, and operator-facing prototypes. When a project needs several analog channels but very little panel space, the board becomes a dependable multi-channel analog controller that can sit beside an M5 core controller or another ESP32 node.

Why choose it over individual analog knobs?Because the integrated structure, RGB feedback, and I2C interface make M5Stack 8Angle Unit easier to wire and easier to reuse than a custom knob array, especially when we want one multi-channel analog controller instead of several separate analog parts.
