INTRODUCTION/OVERVIEW
MD10C is another version of the MD10B which is designed to drive high current brushed DC motor up to 13A continuously. It offers several enhancements over the MD10B such as support for both locked-antiphase and sign-magnitude PWM signals as well as using full solid state components which result in faster response time and eliminate the wear and tear of the mechanical relay.
The MD10C has been designed with the capabilities and features of:
- Bi-directional control for 1 brushed DC motor.
- Support motor voltage ranges from 5V to 25V 30V (for Rev3.0).
- Maximum current up to 13A continuous and 30A peak (10 seconds).
- 3.3V and 5V logic level input.
- 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 (Actual output frequency is the same as input frequency).
- Support both locked-antiphase and sign-magnitude PWM operation.
- The new MD10C can be powered from a single power source and an external Vin is not required.
- Support TTL PWM from the microcontroller, not PWM from the RC receiver.
- Dimension:75mm x 43mm
*MD10C is now Revision 3.0.
** Rev 3.0 can support motor voltage range from 5V to 30V

BOARD LAYOUT AND SPECIFICATION
- Terminal Block – Connect to motor and power source.
Pin No.| Pin Name| Description
---|---|---
1| POWER +| Positive Supply
2| POWER –| Negative Supply
3| Motor Output A| Connect to motor terminal A
4| Motor Output B| Connect to motor terminal B - Red LED A – Turns on when the output A is high and output B is low. Indicates the current flows from output A to B.
- Red LED B – Turns on when the output A is low and output B is high. Indicates the current flows from output B to A.
- Test Button A – When this button is pressed, current flows from output A to B, and the motor will turn CW (or CCW depending on the connection).
- Test Button B – When this button is pressed, current flows from output B to A and the motor will turn CCW (or CW depending on the connection).

DIMENSION
GETTING STARTED
MD10C is compatible with 2 types of PWM operation, which are:
- sign-magnitude PWM – For sign-magnitude PWM operation, 2 control signals are used to control the speed and direction of the motor. PWM is fed to the PWM pin to control the speed while the DIR pin is used to control the direction of the motor.
- Locked-Antiphase PWM – For locked-antiphase PWM operation, only 1 control signal is needed to control the speed and direction of the motor. The PWM pin is connected to logic high while the DIR pin is being fed with the PWM signal. When the PWM signal has a 50% duty cycle, the motor stops running. If the PWM has less than 50% duty cycle, the motor will turn CW (or CCW depending on the connection). If the PWM signal has more than 50% duty cycle, the motor will turn CCW (or CW depending on the connection).
Sample source code for using PIC16F877A to control the motor with MD10C is provided and is available for download at Cytron’s website under the product page. SK40C is used in the demonstration and the connection diagram is as follows:
- Connect MD10C and SK40C as shown in the schematic above and select the board supply for MD10C.
- Upload the hex file into SK40C using UIC00A/B. The hex file can be downloaded from Cytron’s website under the MD10C Sample program. Please refer to SK40C or UIC00B User’s Manual to upload the hex code into SK40C.
WARRANTY
- The product warranty is valid for 12 months.
- Warranty only applies to manufacturing defects.
- Damaged caused by misuse is not covered under the warranty
- The warranty does not cover freight costs both ways.
