The Pololu serial 8-servo controller allows you to control up to eight RC servos with almost any robot controller or computer. The interface to the servo controller is a standard RS-232 serial port or a TTL-level serial line, using any baud rate between 1200 and 38400 baud. Multiple 8-servo controllers can be connected to a single serial line to control up to 128 servos independently. The servo controller is compatible with all of our serial motor controllers and servo controllers. The servo controller is also compatible with the Scott Edwards MiniSSC II servo controller and any software written for it.
All of the ports are conveniently labeled on the back of the PCB. This servo controller can be reset directly from a serial port using the DTR or RTS handshaking lines. Other unique features include individual servo speed and range control. Three diagnostic LEDs get you up and running quickly.

You can purchase the servo controller as a partial kit that requires soldering of the through-hole components (header pins and DB9 connector) or as a completely assembled unit.

For a tiny version of this 8-servo controller, see our micro serial servo controller. If you are interested in controlling more than 8 servos, you may want to consider the 16-servo controller or the USB 16-servo controller. A pre-programmed microcontroller for the 8-servo controller is available separately in a DIP package for those who want to build the servo controller directly into their own circuit.
