ROBOT . 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 DC Brushed 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.

ROBOT . HEAD to TOE Product User’s Manual – MD30C 4.0 BOARD LAYOUT 1. Power Terminal Block Connect to power source. 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 this is not RC (Radio Control) PWM 3. PWM Source Selector Select the source of the speed control PWM.
ROBOT . HEAD to TOE Product User’s Manual – MD30C 4. Internal PWM Potentiometer Used to control the motor speed when PWM source is internal potentiometer. 5. External PWM Potentiometer Port Connect to the external potentiometer (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).

ROBOT . HEAD to TOE Product User’s Manual – MD30C 6.0 HARDWARE INSTALLATION AND GETTING STARTED 6.1 Power and Motor Connection We recommend to use battery as power source to MD30C. The 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.

ROBOT . 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.
ROBOT . 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. The recommended resistance for external potentiometer is 10K Ohm. Created by Cytron Technologies Sdn. Bhd.
ROBOT . HEAD to TOE Product User’s Manual – MD30C External potentiometer is connected on JP5. Please use potentiometer or Variable Resistor with value of 10K Ohm. It can be direct solder, just make sure the pads are clean from flux or any solder ball. Created by Cytron Technologies Sdn. Bhd.
