Unit 8Servos2-Chain 8-Channel Servo Cascade Control Unit STM32G031G8U6 Controller UART Communication Interface Beskrivelse

Unit 8Servos2-Chain is an 8-channel servo cascade control unit with an integrated STM32G031G8U6 core controller. It adopts a UART communication interface and is compatible with the Chain series UART serial cascade communication protocol.
It 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 serve as the input and output interfaces of the Chain series protocol, enabling chained connections of multiple 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, a power interface status indicator, and a HY2.0-4P interface undervoltage status indicator 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
