The Lynxmotion SSC-32U USB Servo Controller is the latest version of the very popular SSC-32 servo controller board. It has a USB port, an Xbee socket, improved power circuit, and a many other improvements.

Lynxmotion SSC-32U Servo Controller
The Lynxmotion SSC-32U Servo Controller is a small preassembled servo controller with some big features. It has high resolution (1uS) for accurate positioning, and extremely smooth moves. The range is 0.50mS to 2.50mS for a range of about 180°. The motion control can be immediate response, speed controlled, timed motion, or a combination. A unique "Group Move" allows any combination of servos to begin and end motion at the same time, even if the servos have to move different distances. This is a very powerful feature for creating complex walking gaits for multi servo walking robots. The servo's position or movement can be Queried to provide feedback to the host computer.

There is even a 12 servo Hexapod sequencer built in. This allows complete control of all aspects of the alternating tripod gait simply by transferring a few values from the host controller. Any output pin can be used as a TTL level output. There are 8 analog inputs pins for reading sensor values, and 6 of them can be used as static or latched digital inputs, so you don't have to worry about missing a short event.

The new SSC-32U board has improved power and communication management. The board still has three terminal blocks, but the new power circuit means that most of the time you will only need to use VS1. With the new board, the logic circuits have large capacitors to protect against brownouts, and the logic has auto power select so the VL=VS1 jumper isn't needed anymore. For communication, in addition to having USB on-board, the SSC-32U has an Xbee socket for easy use with wireless devices such as XBees and Bluetooth.

SSC-32 Servo Sequencer Utility (created using FlowBotics Studio)

The Lynxmotion SSC-32 Servo Controller board can be easily controlled with the new SSC-32 Servo Sequencer Utility. It is available as a free downloadable utility which makes it easy to experiment with robotics and animatronics. It can be found in the Useful Links section.

This utility is an example of the type of program which can be built using FlowBotics Studio (Download) , which includes this program as an open source demo project. The SSC-32 Servo Sequencer Utility program enables you to easily move servo motors, calibrate their position, store and playback motion sequences, upgrade the SSC-32 firmware and more.

Great Unit

This is a second SSC-32U for me. It is a backup for the one on the LynxMotion AL5D Robotic Arm that I have. Also, it is my standalone unit for development testing. The Speed and Time command options are fantastic, not something you see in other micro-controllers


Works like it should, hexapod is walking... only thing i couldn't connect it with the hexapod cilibration tool. but there are alternative which did work. so no problem.

Great Documentation

Very good product with great documentation. Easy to use normally or integrate into a custom system.

Good product but no instructions that were easy to find.

I like the product but they need to cover items on an in-depth video. I got the item working with servos but what about inputs and outputs. Are they TTL based? if so then why not make it simple closed circuit continuity so you don't have to wire resistors etc? show examples. How do you make the transition of if this switch turns then make the X servo stop in the programming. No videos on any of this. Put them easy to find-right beside product and not hidden somewhere deep in youtube. What about bluetooth can you run it on your phone? show examples

Fantastic board

Firstly, I actually ordered this in attempt to control *SMART* servos instead of normal digital servos -- this board will NOT run smart servos! However, with digital servos and such (read the manual), you'll find that it works wonders. It's compatible with Arduino, so you don't need to use the software to get things moving every time, which is always a good thing. The package itself from Roboshop came very professionally packaged in a 8x4x4 box with Roboshop tape, lots of padding paper in the box, and inside they even include the usb connector for it. The PCB board it was printed on was very high quality from Lynxmotion, soldering was perfectly good, and it was brand new. If you're wanting to run servos, even if it's just a few, I can't recommend this enough!
