Overview

Yahboom Single-channel dual PWM servo control debugging board is a plug-and-play servo control debugging board designed for PWM servos in DIY smart robotics. With an on-board STC8G1K08A chip, it can generate PWM signals without writing any program. Servos can be controlled either by turning the potentiometer knob or by using the mode switch button to change operating modes. Power can be supplied via Micro USB (5V) or a KF301 (6–8.4V) terminal block, making it convenient for bench testing and portable builds.

Key Features

  • Single-channel servo controller with dual 3-pin servo interfaces; two servos can be adjusted at the same time through a single knob.
  • Supports three control modes: Manual (knob control), Centering mode (one-key to 90°), and Reciprocating mode (0°–180°).
  • On-board potentiometer knob and function/mode switch button.
  • Wide voltage support for servo debugging: 5–8.4V (use the servo’s rated voltage as reference).
  • Dual power supply ports: Micro USB (5V) and KF301 terminal block (6–8.4V) (two power sources cannot be used at the same time).
  • Compatible with Lego bricks.
  • Hardware debugging accessory (no software and data).

How to Use

  1. Supply power to the controller. The voltage can be 5–8.4V; use the servo’s rated voltage as reference.
  2. Plug the servo into the 3-pin servo interface: + is positive, - is negative, and S is the signal terminal.
  3. Default after power-on is potentiometer control (red LED on). Turn the knob to rotate the servo synchronously.
  4. Press the button to switch modes:
    • Centering mode: Return to the center position (90°). Red LED off; blue LED on.
    • Reciprocating mode: 0°–180° reciprocating rotation. Red and blue LEDs flash alternately.
    • Manual mode: Knob control. Blue LED off; red LED on.

Applications

  • Servo test and model/robot actuator control
  • Mechanical claw test
  • Robotic arm test
  • DIY smart robotics projects

Use Notes

  • Servos can draw high current; ensure the power supply current is sufficient to avoid abnormal behavior.
  • Micro USB input is 5V; terminal block input is 6–8.4V.
  • Do not use the Micro USB and terminal block power inputs at the same time.

Compact 49.5 × 35 mm board layout for easy bench testing and integration into DIY robotics builds.

Manual mode demo controlling a servo with the potentiometer knob on the single-channel PWM controller

Manual mode provides direct knob control for smooth, synchronous servo adjustment.

Centering (90°) and reciprocating (0–180°) mode examples using the mode switch button with a servo

Use one-key centering to return to 90°, or run automatic 0°–180° reciprocation for quick motion checks.

Two power options: KF301 terminal block (6–8.4V) and Micro USB 5V input for servo testing

Power the board via Micro USB (5V) or the KF301 terminal block (6–8.4V)—use only one power source at a time.

How-to-use steps for connecting power and a 3-pin servo and switching between control modesExample applications: servo test, mechanical claw, robotic arm, and robot motion debugging with the controller

Suitable for common servo test tasks like grippers, robotic arms, and small robot mechanisms.

Controller connected to a high-torque digital servo, highlighting 5–8.4V servo compatibility

Designed for PWM servos across a wide input range (5–8.4V), based on the servo’s rated voltage.
