M5Stack Unit 8Servos2-Chain

M5Stack Unit 8Servos2-Chain is an 8-channel servo cascade control unit with an integrated STM32G031G8U6 core controller. This device uses a UARTcommunication interface and is compatible with the Chain series UART serial cascade communication protocol. The Unit 8Servos2-Chain features DC 9V to 24V input and integrates an SY8303AIC step-down circuit to provide a 5V supply at 3A maximum total output current. This device incorporates eight configurable I/O channels that support multiple operating modes, including servo control, digital input/output, ADC input, RGB LED control, and PWM output. An onboard INA199A1DCKR current-detection circuit can sample the total servo current, input voltage, 5V supply voltage, sampling circuits, and power status indicators. Typical applications include multi-servo control, robot joint drive, smart toys, and STEAM education.
