7A / 160W dual DC motor drive module, high-power
industrial grade, positive and negative, PWM speed,
L298 logic
Product parameters:
Power supply voltage DC 6.5V-27V, the power cannot be connected to
reverse or over DC 27V, or may burn the module, it is recommended
connecting in series 15A fuse in the power input.
Dual motor interface, each rated output current 7A, peak current 50A,
the motor interface cannot short-circuit, the proposed series 10A fuse.
Control signal voltage DC 3-6.5V, respectively, is the enable signal and
the positive inversion control signal.
Enable signal terminal (ENA) input PWM adjustable speed, PWM
frequency range 0-10KHZ, PWM minimum pulse width 10us.
Working temperature -25 ℃ -80 ℃.
Product size: 55 * 55 * 16mm (length and width).
Installation hole diameter: 3mm, pay attention to prevent short circuit
on the back of the circuit, you can add insulation pad or copper column
to raise the circuit board.

Product Highlights:
Double H bridge, which can drive two DC motors, single 7A current, high
power;
Wide voltage input range: DC 6.5V - 27V.
Signal optocoupler isolation input, IO port can be directly controlled,
without interference;
Under voltage protection, to prevent instantaneous high-current burned
module;
High power TVS and electrostatic discharge circuit, inhibit the transient
interference pulse and static, enhanced EMC performance, made stable
and reliable product, which are industrial design.

Suitable for motor parameters:
Rated voltage 24V of the motor, the appropriate identification of rated
power 115W and below or rated current of 7A or less the following long-
term work of the motor.
Rated voltage 12V of the motor, the appropriate identification of rated
power 40W and below or rated current 7A rated below the motor for a
long time full of work.
Precautions:
Drive power must not be reversed, the proposed power connector in
series 15A fuse, the voltage should be between DC 6.5 ~ 27V. If the
voltage is over-voltage, power-on may burn the drive module.
It is recommended that the rated output current of the power supply be
at least 2 times of the rated power supply, in case the power supply
voltage cannot reach the required input voltage of the motor when it is
started, which will lead to off output, then causing motor pause for
under voltage protection.
Do not short-circuit the motor interface, or may burn the driver module,
the proposed electrical interface in series 10A fuse.
When switching the forward and reverse, the motor needs to brake more
than 0.1S then reverse; cannot reverse when the motor is not stopped,
otherwise it may damage the drive.
When the drive module is powered down, don't rotate the motor directly
or indirectly at high speed, otherwise the electromotive force generated
by the motor may burn the drive module. If the application requires a
high-speed rotation of the motor when the drive module is powered
down, it is recommended that a relay (NO and COM) be connected in
series to the motor interface of the drive, and then the relay coil and the
drive are connected in common. In this way, when the power down, the
relay will disconnect the drive from the motor.
CAUTION Do not expose the drive to moisture. Do not short-circuit the
components on the drive board. Do not touch the pins and pads on the
board.
