Servo - Hitec HS-35HD (Ultra Nano Size)

This is one of the smallest servos we carry but don't let its size fool you, the HS-35HD is a durable and strong little servo thanks to its Metal-Karbonite gear train! The HS-35HD is only able to take in 4.8 volts and deliver 11.11 oz-in. of maximum torque at 0.1sec/60°, and this guy is only about the size of a penny!

This high quality servo is perfect for your mechatronic needs and if you are looking to get into robotics, this is where to start. The HS-35HD servo comes standard with a 3-pin power and control cable and all hardware listed below.

Note: Check the neutral position before linkage connection. Be advised that this servo is designed to rotate in 360° when the power is off due to its tiny structure. Check the "Neutral Position Warning Instruction" (included with each HS-35HD) for more information.

How to use the SparkFun Servo Trigger to control a vast array of Servo Motors, without any programming!

Hobby Servo Tutorial

May 26, 2016

Servos are motors that allow you to accurately control the rotation of the output shaft, opening up all kinds of possibilities for robotics and other projects.

Core Skill: Robotics

This skill concerns mechanical and robotics knowledge. You may need to know how mechanical parts interact, how motors work, or how to use motor drivers and controllers.

3 Robotics

Skill Level: Competent - You may need an understanding of servo motors and how to drive them. Additionally, you may need some fundamental understanding of motor controllers.
See all skill levels

Core Skill: DIY

Whether it's for assembling a kit, hacking an enclosure, or creating your own parts; the DIY skill is all about knowing how to use tools and the techniques associated with them.


Skill Level: Noob - Basic assembly is required. You may need to provide your own basic tools like a screwdriver, hammer or scissors. Power tools or custom parts are not required. Instructions will be included and easy to follow. Sewing may be required, but only with included patterns.
See all skill levels

Core Skill: Electrical Prototyping

If it requires power, you need to know how much, what all the pins do, and how to hook it up. You may need to reference datasheets, schematics, and know the ins and outs of electronics.

3 Electrical Prototyping

Skill Level: Competent - You will be required to reference a datasheet or schematic to know how to use a component. Your knowledge of a datasheet will only require basic features like power requirements, pinouts, or communications type. Also, you may need a power supply that?s greater than 12V or more than 1A worth of current.

    Front page - "about the size of a nickel" Product page - "only about the size of a penny" And picture is next to the quarter.

    Would it be okay if I used 5V instead of 4.8V on this servo? I was hoping to re-use the 5V pin from a voltage regulator I already have.

    In case you are confused by this:
    description ... designed to rotate in 360° when the power is off
    features .... Rotation: 180°

    To clarify, its controlled range is 0-180° (practical limits about 10-170°), and seeks 90° at idle/power-on unless you immediately give it a signal. With no power and excess load, it can rotate continuously as there are no internal stops. This is demonstrated n the video.

    Hi, When can I order the servo Hitec HS-35HD (Ultra Nano Size)? - It's really important. Thanks...

  • GraysonR / about 10 years ago / 1

    How strong is the case?

  • JGuthridge / about 11 years ago / 1

    How many milliamps do these draw at idle, service use, and stalled?

  • Dimensions are 'all over the place'. Look at data sheet. You have big nickels. Check out Heli-Max hmxm2037 for small and digital (not analog) and 10 bucks

  • Member #473433 / about 11 years ago / 1

    Does anyone know what kind of duty cycle you can run these at without overheating them?

    I’m thinking of disabling the encoder and using it purely as a high quality, gear-reduced drive motor in a micro rock-crawler R/C car, but I’m worried that running at 100% duty for extended periods may wear the little guy out.

    Any thoughts?
