MD13S has great improvement in current protection which MD10C does not have. With new circuit and design, MD13S is able to limit and support current up to 30A max(10 seconds). And the continuous current is at 13A without heatsink (at room temperature of 25°C).
Not to forget it is GROVE compatible, so get yourself a Grove shield. Oh, did I mention? MD13S is smaller than MD10C :)
Nonetheless, it is compatible with Arduino, even Arduino or Raspberry Pi that generate 3.3V logic PWM.
DC brushed motor is the most commonly used and widely available motor in the market. Getting the motor to rotate is fairly easy, just connect the two terminals to power source and it will start spinning, that's the beauty of DC brushed motor. Yet, if you want to control the speed, direction, activation and automate all these functions, check out this tutorial: 5 easiest ways to control a DC motor. And a motor driver is one of the ways. MD10C is one of Cytron's motor driver series which offers easy to use features.
Bi-directional control for one Brushed DC motor (Single Channel).
Support motor voltage ranges from 5V to 30VDC.
Maximum current up to 13A continuous and 30A peak (10 seconds).
3.3V and 5V logic level input, compatible with Arduino and Raspberry Pi.
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 (output frequency is same as input frequency).
Support both Locked-Antiphase and Sign-Magnitude PWM operation. **Note that it is not "RC PWM"
