Cytron Dual Channel 10A DC Motor Driver MDD10A

Got this for a mini Mars-style recon rover I’m making. Buying cheapo no name parts is always a gamble but Cytron seems to be more of an established brand than the usual bargain bin things you can find. The driver is easy enough to use, and has a really cool testing feature for both backward and forward operation. You can tell the solder joints and screw terminals were made with good materials. I am driving 2x24V motors at 3 amps each with lots of braking, switching, and acceleration involved and this little board has held up wonderfully. Definitely worth the extra to get something like this for your project.

Used two of these boards for an ROV project that are wired to four bilge pump (brushed) motors as thrusters. Controlled via GPIO pins on a Raspberry Pi. Aquired four more for larger ROV project.

In my installation, it is possible that the motor wiring was generating some EMI (noise) back to the input signals because it was working ok for a bit, then when I switched direction, it created this tremendous "chatter" and then ceased to work. I know H-bridge drivers like this are supposed to have built in delay functions that prevent the bridge from short circuiting when changing direction, but I wonder if the direction is changed rapidly, if this delay circuit gets "confused" and short circuits anyway. Or maybe the diode that absorb the motor inductive energy during that delay period can only handle a certain number of direction switches per second before overheating and frying. Anyway, I bought 3 of these units, and 2 of them fried within a minute of use. I'm keeping the 3rd unit to use in an application that won't have rapid direction changes, and also smaller motors. I'm hoping it doesn't fry also.

Has a loud electric whine , functions fine
