Is Roboteq motor driver compatible with Arduino?
It is not directly supported. But the device description lists RS232 port that can be interfaced with an Arduino using a TTL to RS232 converter. The description also mentions "several Analog, Pulse and Digital I/Os which can be remapped as command or feedback inputs, limit switches, or many other functions" so it is totally possible to control the controller with an Arduino, but depending on the method you choose it may require some effort.
