Cytron SC08A 8-Channel Servo Controller

The Cytron SC08A 8-Channel Servo Controller is designed for makers, students, robotics hobbyists, and educators who need smooth, precise, and independent control of multiple RC servos.

With support for 8 servo channels, UART communication, wide pulse control (0.5 ms–2.5 ms), and 8000-step resolution, this Cytron controller ensures highly accurate servo positioning – ideal for robotic arms, animatronics, pan-tilt setups, and DIY automation projects.

It also provides extended compatibility through daisy-chain expansion, giving users the ability to control up to 16 servos with two SC08A boards.

What makes the Cytron SC08A stand out is its user-friendly design paired with advanced features like individual servo activation, configurable startup positions, servo ramping, and optional position reporting.

Whether you’re programming with a PC via USB-to-UART or using a microcontroller like Arduino or Raspberry Pi, the Cytron SC08A delivers reliable, flexible, and beginner-friendly RC servo control that fits both educational and professional robotics applications.

Features:

• Cytron’s reliable 8-channel servo controller allows each RC servo to be driven independently with precise and smooth positioning.
• Supports daisy-chaining of two Cytron SC08A boards, enabling up to 16 servos to be controlled simultaneously for advanced robotics builds.
• Offers servo activation control, allowing any channel to be enabled or disabled at any time for safer and more flexible operation.
• Startup position customization lets users pre-set the initial position of each servo for predictable behavior at every power-up.
• Wide 0.5 ms to 2.5 ms pulse range ensures compatibility with most RC servos and allows near-180° rotation.
• High-resolution 8000-step timing ensures accurate servo movements with 0.25 μs precision.
• UART communication at 9600 baud, compatible with PCs (via USB-to-UART) and microcontrollers.
• Compact Cytron design (49 mm × 46 mm) suitable for space-constrained robotics and DIY projects.
• Cytron GUI software allows easy servo testing and control directly from a computer.
