Servo Controller Module 5-30V PWM Signal Converter for RC Models
Servo Controller Module 5-30V PWM Signal Converter for RC Models
Multifunctional Servo Controller & Steering Gear Control Module for RC Models
Take your RC model builds and DIY modifications to the next level with this precision-engineered Multifunctional Servo Controller Module. Featuring a wide 5–30V input range, 12-bit ADC resolution, and adjustable PWM output, this compact converter gives you unmatched control over servo range, speed, and direction — all in a board measuring just 26×10mm.
Key Features
- High-Precision 12-Bit ADC: With 4096 resolution points (vs. only 256 on standard 8-bit controllers), you get dramatically finer servo positioning and smoother movement.
- 16-Bit PWM Hardware: Hardware-level PWM with 65,535 resolution steps ensures ultra-smooth and accurate signal output.
- Adjustable Swing Range: Rotate the onboard potentiometer clockwise to expand or counterclockwise to reduce the servo's swing range — fine-tune it to your exact build requirements.
- Adjustable Speed/Timing: Clockwise rotation of the speed potentiometer accelerates the servo's movement; counterclockwise rotation slows it down for precise control.
- CW / CCW Direction Toggle: Flip the onboard switch left for standard (positive) servo operation or right for reversed (negative) servo operation. Takes effect after power cycle.
- Wide Voltage Compatibility: Accepts 5V to 30V input, making it compatible with a broad range of RC power setups and battery configurations.
- Compact & Lightweight: Board dimensions of just 26×10mm and a 100mm servo lead make it easy to integrate into tight RC model enclosures.

Important Notes
- Colors may appear slightly different due to monitor/screen settings and lighting conditions.
- Please allow ±1–10mm tolerance due to manual measurement.
- The CW/CCW direction change takes effect only after the module is power-cycled (switched off and back on).

Frequently Asked Questions
Q: What is the advantage of a 12-bit ADC over a standard 8-bit servo controller?
A: A 12-bit ADC provides 4096 resolution points compared to just 256 on an 8-bit controller. This means significantly finer positioning, smoother servo travel, and more precise control — ideal for demanding RC model applications where accuracy matters.
Q: What RC applications is this servo controller module compatible with?
A: This module is suitable for a wide range of RC model applications including cars, boats, aircraft, robotics, and DIY custom builds. Its 5–30V input range makes it compatible with most standard RC battery and power configurations.
Q: How do I reverse the servo direction with this module?
A: Simply toggle the onboard switch to the right for reverse (CCW) servo operation, or to the left for standard (CW) operation. Note that this change will only take effect after you power the module off and back on again.
Q: Can I adjust both speed and range independently on this module?
A: Yes. The module features two separate onboard potentiometers — one controls the swing range of the servo and the other controls the movement speed — allowing you to fine-tune each parameter independently for your specific RC model setup.
