Smart Drive Duo-10
Introduction
If you need a DC brushed motor driver that can accept signals from:
- RC (Radio Control)
- PWM of microcontroller
- Analog voltage of Potentiometer/Variable Resistor
- UART/Serial command of microcontroller
Well, this motor driver is perfect for you, and it supports up to 10 Amps (continuous) each channel. It will be easy to build combat/sumo robot. Not to forget, you can configure MDDS10 to drive two channels motor in independent or mix mode. SmartDriveDuo10 has the specification of MDD10A which can drive two brushed motors bidirectionally at 10Amps each, plus additional smart features of MDS40A.
The operation mode is configured by the DIP switch on MDDS10. The DIP switch configurations for commonly used modes are printed at the back of PCB. MDDS10 uses solid-state component - MOSFETs as H-bridge switching which offers faster switching time. And the MOSFETs are being switched at 16KHz for quiet operation. And with MOSFETs, no flyback diode is needed :) With the onboard temperature sensor, this smart driver is able to reduce the output current stage by stage to prevent it from overheating and burning!
Features:
- Input Voltage (Motor): 7 - 35VDC
- Single power operation
- Dual Channels, can drive two brush motors bidirectionally, independently, or mixed as differentiated drive.
- Operating modes:
- RC (RC servo signal)
- Analog
- PWM
- simplified and packetized UART
- Support Sign-magnitude and Locked antiphase in PWM mode.
- Two manual/test buttons for each channel.
- Two output indicator LEDs for each channel.
- Power, Error indicator, RUN status (Left and Right) LEDs.
- The Error LED will indicate:
- Error Input (Blinks 2 times), check the input signal and the operation mode
- Under Voltage (Blinks 3 times), the battery voltage is low.
- Over Voltage (Blinks 4 times), the supply voltage is higher than 35VDC, it will stop operating
- Over temperature (Blinks 5 times), the board temperature is high
- Shut down (Blinks 6 times), board temperature is too high, the board will stop working.
- On board reset button to restart the MCU after changing operation mode on DIP switch.
- Full solid state MOSFET for better efficiency and eliminates the need for external flyback diodes.
- Regenerative Braking.
- Temperature feedback to reduce output current and prevent overheating of MOSFET.
- Support up to 10A continuous current at room temperature (25ºC).
- Support up to 30A peak for 10 seconds. Output will be reduced with the temperature raises.
- Suitable for combat or sumo robots.
- 16KHz switching frequency for quiet operation.
- On-board switching voltage regulator for higher power efficiency.
- Battery low voltage monitoring and indicator.
- We have tried this driver with a single power window motor at 24V, full load without smoke coming out :)
- NO polarity protection, please double-check the power input connection.
- Dimension: 66.8mm x 101.09mm.
