Here is a simple, low-cost, high quality servo for all your mechatronic needs. This servo is very similar in size and specifications to the Hitec HS-55. This little guy is able to take in 6 volts and deliver 20.8 oz-in. of maximum torque at 0.10 sec/60°
This small servo comes with a standard 3 pin power and control cable, and all hardware listed below.
Note: This servo is rated for 180° rotation, but in actuality it only hits ~160°.
This servo is used in our SparkFun Inventor's Kit. For more information on using this tutorial with Arduino, check below:
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.
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.

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.

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.
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.

I build Raspberry Pi pan and tile cameras with two of these servos. They work great, are light weight, and don't cost much.

It has a hard time staying in position, it's shaking out of control rendering it unusable.
I got 4-5 of these, and they're good for prototyping. If you want to make high-quality products you may not go here (and there are higher quality options in here).
As usual you'll have to experiment with the pulse width to map the full range of motion, and don't go too high or low or it will keep forcing against the hard limits.
For some reason I've fried one of mine so that when I power it on it just pushes against the limit and does not respond to any valid input signal anymore, but it was probably my fault.
Get a few of them and experiment with them.
It was easy to hook up and easy to control. At times, there is some chatter but this is common for servos. the rotation only hits about 160 degrees but that was clearly stated.
I was using this for some simple projects with my kids. It worked the first 3 times, and then was like watching a dying insect sort of jerking around. I think I'll spend a little extra cash on a better one next time.
One of them burned out really quickly but the other two ended up being decent enough and the right choice for the pan/tilt bracket they are attached to.
I'm just learning to use servos in projects and this was a nice, inexpensive way to build a little pan-tilt project and not worry about breaking my bank account if I broke the project.
Using this as a pen lift in a plotter and it is working great so far
Servo jitters severely around 0 position and makes lots of noise. Also the terminals and wire seem a bit flimsy. I would trust this servo in $5 pan tilt bracket but NOT in a $200 model airplane!
Hi, Sorry about the issues. If you need a more reliable servo for high value projects, I would recommend a higher grade servo such as the HiTec servos. They are much more reliable than the generic servos. But the generic servos are great when you need a low dollar servo for your applications. Thanks for the feedback!
