Pololu jrk motor controller voltage and current limit


I’m currently using pololu jrk motor controller 21v3, and was wondering what the voltage and current limit for these boards are. I connected it with 12V before and it worked fine, but sometime later I get a problem when reading from the serial port, and one of the things I changed was switching power supply to 24V, despite remembering the board can take up to 28V or so.


Using a 24V power supply should be fine (as long as it is not a battery). What other things have you changed in your system? Could you tell me more details about the serial port problem you are having? If you are getting an error message, could you post what it is?
