Pololu 3423 FEETECH Mini Servo FT1117M
The Pololu 3423 FEETECH Mini Servo FT1117M is a compact, lightweight servo motor engineered for precision positioning and motion control in space-constrained applications. Roboticists, drone developers, and embedded systems engineers rely on this servo for its exceptional torque-to-weight ratio and digital control capabilities. This servo solves the critical challenge of achieving reliable angular positioning in miniaturized projects where traditional servos are too large or power-hungry.
Product Overview
The FEETECH FT1117M is a digital servo utilizing a brushless motor architecture with integrated control electronics, delivering smooth and accurate position feedback through pulse-width modulation (PWM) control signals. The servo operates on a closed-loop feedback system that continuously monitors shaft position and adjusts motor output to maintain commanded angles with minimal overshoot. Its lightweight aluminum gear train provides excellent durability while maintaining a compact footprint ideal for robotic arms, pan-tilt mechanisms, and autonomous systems requiring multiple servo coordination.
This model stands out through its dual-bearing design that reduces friction and extends operational lifespan, combined with metal gears that withstand sustained load conditions better than plastic alternatives. The servo features a wide operating voltage range, making it compatible with both battery-powered and regulated power supplies common in robotics projects. Built-in protection circuits safeguard against voltage spikes and stall conditions, ensuring reliability in demanding field applications.

How to Use
Connect the servo to your microcontroller using three wires: power (red), ground (black), and control signal (yellow/white). Supply 5V regulated power from a dedicated servo power supply to avoid voltage sag affecting control accuracy. Program your microcontroller to generate standard PWM signals on the control pin, typically ranging from 1000 microseconds (minimum position) to 2000 microseconds (maximum position), with 1500 microseconds representing center position. Most Arduino-compatible boards use the Servo.h library which abstracts pulse generation, allowing simple angle commands like servo.write(90) for 90-degree positioning.
For multi-servo applications, ensure adequate power supply capacity—each servo draws approximately 100-200mA at stall torque. Use separate power distribution boards or servo controllers to prevent voltage drops across long wire runs. Implement software debouncing and position verification loops to confirm servo movement completion before executing dependent operations. When operating multiple servos simultaneously, stagger command updates by 10-20 milliseconds to prevent power supply inrush currents that could trigger protection circuits or reset microcontroller logic.
Frequently Asked Questions
What is the maximum continuous torque this servo can deliver without overheating?
The FT1117M delivers 1.8 kg-cm stall torque at 5V, but continuous operation should limit load to approximately 60-70% of stall torque to maintain thermal stability. Extended operation above 1.2 kg-cm under continuous load may cause internal temperature rise. For sustained high-torque applications, implement duty-cycle control or mechanical load reduction through gear reduction stages.
Can I operate this servo at 7.2V or higher voltage for increased speed and torque?
No, the FT1117M is rated for maximum 6.0V DC operation. Exceeding this voltage damages internal control electronics and motor windings. If higher performance is required, consider Pololu's larger servo models rated for extended voltage ranges, or use mechanical gear reduction to increase effective torque while maintaining servo voltage specifications.
How do I determine if the servo is receiving correct PWM signals?
Use an oscilloscope or logic analyzer to verify pulse width at the control pin. Valid signals show pulses between 1000-2000 microseconds repeating at 50Hz frequency. If pulses are outside this range or frequency is incorrect, the servo enters failsafe mode and centers. Check microcontroller code for proper Servo.h library initialization and pin configuration.
What is the resolution and positioning accuracy of this servo?
The FT1117M provides approximately 1-degree resolution across its 180-degree range due to digital feedback control. Actual positioning accuracy is typically within 2-3 degrees under normal operating conditions due to gear backlash and control loop response characteristics. For applications requiring sub-degree accuracy, implement closed-loop feedback using external potentiometers or magnetic encoders.
