Up to 16 GO servomotors supported with 4 sets of 3pin connectors for efficient, organized wiring. Stable voltage for reliable performance: includes a 10 V 1000uF capacitor to help maintain a stable external input voltage for constant servomotor yield. Overload protection: 220 ohm resistors integrated in the PWM output lines guard against overloads and ensure reliable operation during LED conduction. Flexible control: can be driven by a 3.3 V microcontroller and deliver safely up to 6 V, offering broad compatibility and straightforward integration. Key specifications at a glance: supports GO servomotors up to 16 units; wiring via 4 x 3pin connector groups; external supply with a 10 V 1000uF capacitor; PWM lines include 220 ohm resistors for protection; control input compatible with 3.3 V microcontrollers; output voltage safe up to 6 V. Physical and compatibility notes: size and material details are not specified in the description; the information provided focuses on function, compatibility with GO servomotors, and protection features. Use scenarios: Robotics prototyping: control a multiservo robotic arm or small robot using a 3.3 V microcontroller while maintaining stable servo performance from a shared supply. Educational projects: teach PWM, servo coordination, and power management with a single, scalable servo hub. Demonstrations and hobby builds: synchronize multiple servos for motion sequences in demos, model builds, or light automations that require organized wiring and protection.
