SDC21xx Motor Controller Datasheet 1

SDC21xx

2x20A or 1x40A

High Performance

Dual Channel

Brushed DC Motor

Controller with USB

and CAN Interface

Fitting a very compact 70x70mm board, Roboteq’s SDC21xx

controller is designed to convert commands received from an

RC radio, Analog Joystick, wireless modem, PC (via RS232 or

USB) or microcomputer into high voltage and high current out-

put for driving one or two DC motors. A version with CAN bus

allows up to 127 controllers to communicate at up to 1Mbit/s

on a single twisted pair.

The controller features a high-performance 32-bit microcom-

puter and quadrature encoder inputs to perform advanced

motion control algorithms in Open Loop or Close Loop (Speed

or Position) modes. The SDC21xx features several Analog,

Pulse and Digital I/Os which can be remapped as command or

feedback inputs, limit switches, or many other functions.

For mobile robot applications, the controller’s two motor chan-

nels can either be operated independently or mixed to set the

direction and rotation of a vehicle by coordinating the motion of

each motor. Numerous safety features are incorporated into the

controller to ensure reliable and safe operation. The controller's

operation can be extensively automated and customized using

Basic Language user programs. The controller can be repro-

grammed in the field with the latest features by downloading

new operating software from Roboteq.
