Easy connection Connect 16 servomotors using four groups of convenient 3pin connectors at the same time for straightforward wiring and setup. Stable performance Built with a large capacitor on the V+ line to improve stability, supporting a maximum external input voltage of 10 V. Protected output Each PWM output includes a 220 ohm resistor to drive an LED and protect the circuit, helping with clear status indication. Flexible control 5V compatible design allows control by a 3.3V microcontroller, while the PWM outputs support voltages up to 6V for typical servo operation. Use scenarios Robotics projects requiring synchronized control of up to 16 servos, such as multijoint robotic arms or kinetic models. Educational and prototype development where a 3.3V MCU can drive a 5V PWM controller and observe servo responses. Small automation or hobby setups that need simultaneous servo actuation, such as pan/tilt camera systems or interactive animatronics.
