Has anyone used the Robo Claw 2x30 to operate 12V DC Gear motors? The Robo Claw is basically the same as the Sabretooth 2x25. I have used the robo claw 2x30 using RC control and it works great. I just tried to use it in simple serial mode with the EZ-B. Plugged the R/C cable from D0 on EZ-b to the S1 pins on the Robo Claw. set the dip swith for simple serial and the baud rate switches to 34800. Using the Sabretooth control, Only one wheel turns forward and backwards at a very slow speed. The other wheel does not turn at all. What am I missing?
