LynxMotion SSC-32

Hi Folks
For a Wwile I have been looking at different servo controller boards for a project. Each board has different characteristics which make then easier or more difficult for animatronic control.

One of the more interesting ones is the LynxMotion SSC-32 board. It uses a Atmel ATMEGA168-20PU as its processor and it can have its firmware (open source) updated by the user. There is also a very active forum with people making modifications to the firmware for specialised purposes.

Of real interest to anyone who is doing animatronics is the capability to send a group of commands at once. For example if one wanted to move 10 servo’s to a new point and have them all finish their moving at a specific number of microseconds later you can bundle the commands into one line and send them. The SSC-32 stores the commands until it sees a CR and then processes them.

This makes it very easy to set up sequences being read from a storage card or other system. It also calculates the speed that the servos needs to move to reach their endpoint together. Servos that need to move more will move faster and servos that need to move less will be slower. This takes a lot of load off the controlling program.

There are a lot of other commands that one can investigate and it can be controlled by a simple TTL serial connection. There is a full RS-232 port as well so you can tryout the sequences before saving. It will also chat upto 115K baud.

Additional software can be downloaded or brought depending on the complexity of the sequenced that you want to play around with - but the software IS optional for the purpose… it just makes it easier.

For about $40.00USD it proves to be a very powerful board with a lot going for it.

Hope this helps someone.

P.S. I have no affiliation with LynxMotion. I am a hobbiest animatronics maker.

We used one of their boards on the robot arm we have at the office.

How did you find the SSC-32?

Myself - I often buy boards to try out and see what they can do. Some of the baords can be very basic whilst others can be the reverse.

When the ZX-Servo16U - its a nice board but there is no Group command, nor is there one for the SD-21 from Devantech.

The SCC-32 seems to have all of the commands that I need, plus on their forum there is mention of a newer binary format so that sending commands to the board can be even quicker.

Hope this helps

I own this board and used it on every project involving one or more (18) servo motors.
I have never had any problems at all with this board.

It still runs on the factory firmware, and still working flawlessly.

If you are into robotics or animatronics (or similar) you will love this board.

The best is, fez can control it by using 2 male-female wires (signal+ and ground).

Another option is the Pololu Electronic Mini Maestro series of servo controllers. They have the ability to interface to a PC by USB and serial. Some channels also can be used as 0-5 volt 10 bit A to D. I’ve been using one with a Panda so I haven’t done anything with USB but, the serial works great. Link

SSC-32 can be used with pc too (done in the past) requires a usb-serial cable though.
