ROBOT . HEAD to TOE Product User’s Manual – MDS40B 1. INTRODUCTION Enhanced SmartDrive40 is an enhancement version of SmartDrive40 which is designed to drive medium to high power brushed DC motor with current capacity up to 80A peak and 40A continuously. MOSFETs are switched at 16 KHz to ensure quiet operation and no annoying whining sound. Besides, it also equipped with a microcontroller unit to provide smart features such as multiple input mode, current limiting and thermal protection.

ROBOT . HEAD to TOE Product User’s Manual – MDS40B 5. POWER SUPPLY Enhanced SmartDrive40 supports input voltage ranges from 10V to 45V. The recommended power sources are: ● 6 – 18 cells NiMH or NiCd battery. ● 3 – 6 cells LiPo or Li-Ion battery. ● 10V – 45V sealed lead acid battery. ● 10V – 45V power supply (Must be in parallel with a battery with same voltage). The power source can be connected to Enhanced SmartDrive40 either via the terminal block, or soldered directly to the pad at the bottom layer.
ROBOT . HEAD to TOE Product User’s Manual – MDS40B 6. MOTOR CONNECTION Similar to the power supply, connection to the motor can be made either via the terminal block, or it can be soldered directly to the bottom layer pad. For Mixed mode, especially for RC input mode (or Breakout board with Joystick soldered), each terminal block must be connected to the same side of the motor. For example, left terminal block connected to motor LEFT and right terminal block connected to motor RIGHT.
ROBOT . HEAD to TOE Product User’s Manual – MDS40B 7. SAFETY FEATURES Enhanced SmartDrive40 incorporates some safety features which make it robust and reliable motor driver. Below are the detailed descriptions for each feature. a. Input Error (Error LED blinks 2 times) Every time Enhanced SmartDrive40 is power up, the input data must be ‘stop’ (for RC, Analog, PWM input mode). This feature prevent the driver from sudden run, especially when the driver accidently reset. b.
ROBOT . HEAD to TOE Product User’s Manual – MDS40B 8. INPUT MODE When the Enhanced SmartDrive40 is powered up, RUN LED, ERR LED and OC LED will running once. After that, the input mode will be read from the DIP switch and retained as long as the driver is powered. If you wish to change the input mode, you will need to change the setting on the DIP switch and press the “RST” reset button, or power cycle the driver (Turn it off and turn it on again).

ROBOT . HEAD to TOE Product User’s Manual – MDS40B 8.1 RC INPUT MODE In RC input mode, the speed and direction of the motor is controlled by the signal from the standard hobby radio control transmitter and receiver, or a microcontroller generating the similar signal. NOTE: The RC transmitter must be ON before power up the Enhanced SmartDrive40. RC Input mode is selected by setting the SW1 & SW2 to 0 (Down). SW3 – SW6 can be configured depending on the requirement of the user.

ROBOT . HEAD to TOE Product User’s Manual – MDS40B 8.2 ANALOG/PWM INPUT MODE In Analog/PWM input mode, the speed and direction of the motor is controlled by the analog voltage or PWM signal. The valid input range is 0 – 5V and it’s very easy to control by using a potentiometer. For example, the motor can be controlled by a joystick or foot pedal with potentiometer. NOTE: The Analog/PWM signal to stop the motor (2.
ROBOT . HEAD to TOE Product User’s Manual – MDS40B Mode 0 1 Locked Anti-Phase – Motor stops when the input signal is 2.5V. Motor moves in one direction when the input is < 2.5V and in another direction when the input is > 2.5V. Recommended this mode if controlled using Breakout board with Joystick soldered. Signed Magnitude – Input 1 controls the speed of the motor. Motor stops when the input is 0V and run at full speed when the input is 5V.

ROBOT . HEAD to TOE Product User’s Manual – MDS40B 8.3 SERIAL SIMPLIFIED MODE In Simplified Serial mode, Enhanced SmartDrive40 is controlled by using the UART interface. Input 1 is the UART Rx pin and Input 2 is the Slave Select pin. A single byte of data is all you need to control the speed and direction of the motor. Sending byte 127(decimal) 0r 0b01111111(binary) stops the motor, 0 is full reverse and 255 (decimal) is full forward.

ROBOT . HEAD to TOE Product User’s Manual – MDS40B 8.4 SERIAL PACKETIZED MODE In Packetized Serial mode, Enhanced SmartDrive40 is controlled by using the UART interface. DIG1 pin is the UART Rx pin. DIG2, AN1 and AN2 pins are not used in this mode. To control the motor, data sent to the driver must be in 4 bytes packet format which includes a header, address, command and checksum. Up to 8 units of Enhanced SmartDrive40 can be connected together to a single microcontroller UART Tx pin.
