Unit 8Servos2-I2C 8-Channel Servo Cascade Control Unit STM32G031G8U6 Controller I2C Communication Interface Description

Unit 8Servos2-I2C is an 8-channel servo cascade control unit featuring the STM32G031G8U6 as its core controller. It adopts an I2C communication interface and provides 8x configurable IO channels that support configuring multiple operating modes: servo control, digital input / output, ADC input, RGB LED control, and PWM mode.
Two onboard HY2.0-4P interfaces are connected internally and share the same I2C bus, and a 16-position rotary encoder is provided for flexible configuration of the device I2C address, making it convenient to expand and connect other I2C devices.
This unit supports 9 ~ 24V input and integrates an SY8303AIC step-down circuit to provide a 5V supply, with a maximum total output current of 3A.
An onboard INA199A1DCKR current detection circuit can sample the total servo current, and input voltage and 5V supply voltage sampling circuits as well as power status indicators are also provided, making it suitable for application scenarios such as multi-servo control, robot joint drive, and toys.

Status indication
Red indicator: power interface status indicator (lights when the interface voltage is higher than 8.5V)
Green indicator: HY2.0-4P interface undervoltage status indicator (lights when the interface voltage is lower than 4.5V)
Applications
Multi-servo control
Robot joint drive
toys
STEAM education
