  • On this servo, brown is ground, red is power, and orange is PWM.

  • Be careful if choosing this servo to use with an Arduino with the power supplied by the Arduino. I’m using an Arduino Uno and if I ask this thing to turn any faster than very slow, my Arduino will reset. I believe it’s a power draw issue. It can run the “Sweep” program from the library okay, but you will not get it to turn quickly to any position without the Arduino resetting over and over and then freezing, and needing to be power reset. This happened with two of these servos, so I don’t think it was just a fluke with one.

  • Ambiguity needs to be removed in item descriptions. How do you sell a servo and not specify the range of motion. Mine was 90degrees, apparantly others have a 180 variant. Probably not going to buy servos from Sparkfun anymore (price being the larger factor).

  • I’ve had bad luck with this servo model. Two of them that we purchased burned out pretty quick, as in less than two days of light use. I was using them with PCA9685 16-channel driver. Both of them seemed to burn out, which was noticeable because of the smell. All of the other servos that we have been using the PCA9685 are working fine (continuous and standard).

  • When will there be more in stock.

  • Hi, can I somehow stop and “freeze” this servo’s shaft (rotor) ? Basically i whant to use this servo as an electromagnet, to pull down a little wight which is hanged with a spring. So, i what to rotate with some degrees the rotor and then i whant to brake/freeze the shaft so the spring could not react. Thanks !

    • I believe that whenever a servo has power, regardless of the signal, it will use force to maintain its current position until told to do otherwise.

  • I wish there was more information on the mounting plates (such as dimensions, distance between holes, size of holes, etc), and similar information about the servo itself (dimensions, positioning and size of mounting holes). Is there anywhere I could get this information?

  • What is the little screw included in this package for? I assume the 4 larger screws are for mounting, but I can’t figure out where the little one goes, or what it’s for?

  • How do I use this servo with the Netduino when I want to use it as a steer for a car. I want to steer approximately 40 degrees.

  • I ordered three of these (TowerPro SG-5010) and there seems to be little or no documentation online for them. What documentation I did find was mostly wrong. In the end, I had to figure out the timings via trial and error.

    First of all, they rotate slightly more than 180 degrees, I’d say around 200 degrees. The PWM period is a servo standard 20ms,but the positional timings varied across all three of my servos. The maximum rotational position is achieved at around a 2.8ms pulse. Meanwhile the minimum rotational position is at around a 0.65ms pulse. You might want to try smaller or larger (respectively) values so you don’t try to position it past its maximum and stall the motor.

    In the interest of making this an all inclusive post, as noted by Funda, the wires are: Brown = Ground Red = Power Orange = Control (PWM)

    I hope this helps!

  • anyone could make this one work with arduino?
    I have an Arduino mega board,,,but the Servo library doesn’t quite work,,,,it moves a little bit, returns and thats it.

  • Hello, who is the manufacturer of this product? Thank you.

  • For anyone who needs a servo but isn’t all that sure about the torque range that they will need, these things are perfect. running at only 5v I have yet to get it to stall. They are rated for up to 6v, so I don’t even want to know what they are capable of with more pwr! Absolutely amazing servos, who needs full rotation anyways.

  • Is servo this compatible with the OpenServo board sold here at Sparkfun?

  • Has anyone else had an issue where when you connect the servo to power, it rotates clockwise around 45 degrees? Always happens to me and it’s incredibly annoying - now I need to find a new servo that does NOT do this. If anyone has a fix for this i’m more than willing to retract my comments, however it’s nigh-on unusable for a reverse geocache latch mechanism..
    Also, just to confirm, yes, it’s a 180° rotation servo.

  • Anyone know if a pot modification will work on this servo? I see it can do continous rotation, but I just need a wider range not infinite. Also, is anyone able to find stall current or at least peak current they have seen?

  • Anyone aware of any servo mounting brackets that work with these? There really isn’t much to go buy to tell if they’ll fit. Attempting to use two servos for aiming a camera.

  • Part 1…
    This is a 180degree servo (mine being a TowerPro SG-5010). I finally got around to using mine with my Arduino 2009 board a couple months ago. It died after 1.5 months of light use.
    I really wanted a “medium” grade, but SparkFun was out. Large was overkill but acceptable for the project. I only used it to move a plastic flap back and forth with no real load. It was also noisy as hell and could hear it through the project box all the way into the living room.
    After it died, I could manually rotate it one way with normal resistance, but the other way was very difficult. The gears still feel very tight (no jiggling), so I think those are ok. The bottom plastic cover also has 2 slightly melted points in the middle. I’m betting the board controller blew.

    • Part 2…
      This should have lasted longer. Since it was such a light load, I just powered it off my AVR board which was powered off USB. It’s not like it could over load. I only used about 140 degrees of movement and Arduino refused to let it peg regardless. This was used in a low vibration, low impact environment with lots of air flow. My guess is that it got around 4000 cycles before dying. The sad thing is that this is not even worth trying to RMA. Since these are out of stock right now, I’d recommend SparkFun choose a better brand name for the next round.
      If using with an Arduino (just about any servo, I guess), I also recommend buying “break away male pin headers” to make your own extension/breakout cable.

  • Just incase anyone is wondering, I emailed customer service to ask what the range of rotation is for this servo. Charlie responded to say that they have a 90 degree range. Thanks Charlie!

  • It seems that (if it is the servo from the image) the specifications are not correct. Their site shows different specifications?

  • Do you have a datasheet for this? It appears the company doesn’t have a website.

  • This is continous rotation ? we need data sheet please ! ; )

  • Please I need the datasheet of it

  • Would love a continuous rotation version of this or a tutorial on converting them to continuous rotation. What are our chances of seeing this happen?

  • Yep. I’ll add that to the description.

  • Hi.
    Does this one come with the mounting hardware shown on the picture?

  • Would this be large enough to rotate an arm on a robot. Say…5 lbs. roughly?

    • When it comes to rotation the weight is meaningless. One ounce can be too much, if it is mounted too far from the center of rotation. When perfectly balanced on well lubricated you can move a metric ton with you pinky. Read up on torque (http://en.wikipedia.org/wiki/Torque) - the stall torque of the servo is roughly 5kg*cm
