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 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.
| Note: The Pololu serial 8-servo controller is not a
standalone device: to use it, you must connect it to power supplies, servos,
and a main controller that you program to send commands to the servo controller.
