MDD10A is the dual channel version of MD10C which is designed to drive 2 brushed DC motors with high current up to 10A continuously. Like MD10C, MDD10A also supports locked-antiphase and sign-magnitude PWM signal. It is using full solid state components that result in faster response time and eliminate the wear and tear of the mechanical relay. **Note that it is not for "RC PWM" Features: Bi-directional control for 2 brushed DC motor. Support motor voltage ranges from 5V to 30V (Rev2.0). Maximum current up to 10A continuous and 30A peak (10 second) for each channel. Solid state components provide faster response time and eliminate the wear and tear of mechanical relay. Fully NMOS H-Bridge for better efficiency and no heat sink is required. Speed control PWM frequency up to 20KHz. Support both locked-antiphase and sign-magnitude PWM operation. 2 activation buttons for fast test on each channel. Dimension: 84.5mm x 62mm

Good quality, really happy with this driver
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.

ROV project: Worked great for brushed bilge pump motor.
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.

Unit fried after a minute of use.
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.
