R OBOT . HEAD to TOE Product User’s Manual – MD30C 1.0 INTRODUCTION MD30C is the successor of MD30B which is designed to drive medium to high power brushed DC motor with current capacity up to 80A peak and 30A continuously. Fully NMOS design not only provides faster switching time, it is also more efficient and no heatsink or fan is required.

For high current application, please solder the wire directly to the pad at bottom layer. 2. Input Pin No. Pin Name Description 1 GND Ground 2 PWM * PWM input for speed control. 3 DIR Direction Input. * Note that it is not for RC PWM 3. PWM Source Selector Select the source of the speed control PWM.
R OBOT . HEAD to TOE Product User’s Manual – MD30C 4. I nternal PWM Potentiometer Used to control the motor speed when PWM source is internal potentiometer. 5. External PWM Potentiometer Port Connect to the external potentiometer (5K 10K Ohm). Used to control the motor speed when PWM source is external potentiometer. 6. Test Button A When this button is pressed, current flows from output A to B and motor will turn CW (or CCW depending on the connection).

R OBOT . HEAD to TOE Product User’s Manual – MD30C 6.0 HARDWARE INSTALLATION AND GETTING STARTED 6.1 Battery and Motor Connection Battery and motor can be connected to the MD30C either via the screw terminal block, or it can be soldered directly to the pad at the bottom layer of the PCB. Make sure the battery and motor are connected to the correct port. Connecting battery to the motor port will burn the MOSFET.

R OBOT . HEAD to TOE Product User’s Manual – MD30C 6.2 Standalone Operation The MD30C can operate in standalone mode. In this mode, the motor is controlled by the onboard switches and speed potentiometer. Alternatively, external switches and potentiometer can be used to control the motor. This allow the switches and potentiometer to be mounted at easy to reach place.
R OBOT . HEAD to TOE Product User’s Manual – MD30C External Switches and Potentiometer Set the jumpers as below: JP4 : EXT POT JP6 : INT PWM Connect the external switches and potentiometer as below. Please note that the onboard potentiometer will have no effect when JP4 is changed to EXT POT. Created by Cytron Technologies Sdn. Bhd.
