SmartElex 10D Dual Channel DC
Motor Driver (Powered by Raspberry Pi)

Introduction:
SmartElex 10D is a dual channel motor driver capable of supplying 10
amps continuous with peak currents up to 25 amps (10Sec) per channel. It
can be operated from radio control, analog, TTL serial and PWM. A variety
of operating modes including with mixed and independent mode in radio
control, analog and in PWM mode. Operating modes allow for operation,
such as switching between radio controls and PWM mode or switching
between any of 4 modes via 4 position DPDT mode switch.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 modes and current limit and thermal
protection. If temperature of board is reaches 80 degree then motor speed
becomes half and speed will be normal once temperature reaches below 70
degree. Motor driver will be shut down at 100 degree.

Overview:
Power Input: Connect to a 7V-22V Battery or Power Supply.
Motor 1 and Motor 2 Terminal: Connect Motor 1 to Motor 1 Terminal. Connect
Motor 2 Motor 2 Terminal.
Mode Selection: These are used to set the operating mode and options.
Error (ERR) and Over Current (OC) LEDs: Error LED glows when Under
Voltage Lockout (Input Voltage less than 7V) .Overcurrent LEDs glows due to
current greater than 30 AMP.
RC Input: 2 channel Radio Controller receiver connected to these pins.

Connections/Wiring:
SmartElex 10D can be used with power supplies or batteries. Input power is connected to
the center power terminals labeled VIN and GND. The input voltage range is 7V to 22V. The
input current is dependent on the motors being used and the load placed upon them.
As a general rule of thumb, you should use the thickest wire that is practical to make power
connections, especially on the battery leads. Using undersized wire will lead to the wire
getting hot, and can lead to elevated temperatures on the SmartElex 30D as well.
The main power connections to the SmartElex 10D are on the rear edge of the board.
Connections are made to large black screw terminals. These terminals will accept 10 to 28
gauge wire. Using stranded wire it is possible to run twinned 10 gauge wire connections to
the battery terminals. This is often a good idea if your design will be running both motors
near or above the 10 amp continuous limit. For the motor connections, single 12 gauge wires
should be sufficient for all applications.
