Please take pictures of the encoder signal lines on an oscilloscope and email support@basicmicro.com about this. If the encoder signals are clean and noise free then it could be a problem with the encoders(excedingly rare). Noise is the usual cause of problem. This is especially common on motors wit...

You can not.

The datasheet it being very conservative. Power wires should be kept as short as possible. Use larger gauge wire than you think you need. The longer the wire the larger the wire gauge should be. 3 feet of wire and the power wire being at least the same gauge as the motor wire is ok. Using large leng...

Just click Update firmware. There is no mode button on some models of Roboclaw. The mode button to force bootloader mode is not required. Motion Studio will send a command to tell the unit to go into bootloader mode.

Most mosfet drivers use a boost capacitor to generate the high side gate voltage. This requires recharging the cap which requires turning off the high side for a short period of time. This limits the on-time to around 98%.

The controller is not designed to survive reverse power. It will have instantly damaged the mosfet drivers.

If you still want to try, they are as you determined, 2512 10mOhm. They need to be a minimum of 2watt.

The a4940K chips are almost certainly dead as well.

1. No, there is no speed limit adjustment in the Roboclaw.
2. Logic battery is optional. When not used, the main battery will power logic. The main purpose of the logic battery is to eliminate brownouts due to the main battery being pulled too low by the motors.

Roboclaw does not have any trim functions. With RC mode it is assumed you are using a RC radio which all have trim.

You will need to adjust your RC pulse output in your arduino code. Alternative, we recommned using packet serial commands with arduino and add offsets to the commands as appropriate.

You need to adjust it in your arduino code(left/right value). The Roboclaw does not have any trim functions. Normally RC mode is used with RC radios which have built in trim already.

If you are using an arduino we recommend using packet serial, not RC.

If the motor can't move in one direction(eg when directly wired to a battery) that indicates a broken or shorted connection. If it is a broken connection it would not damage the Roboclaw. If it was shorted it would kill it instantly. Roboclaw can NOT protect against a dead short. It requires a minim...
