Product description: the Pololu High-Power 18v15 - a single-driver engines 30V/15A

Driver based on the MOSFET allows you to control one DC motor, powered by voltage from 5.5 V to 30 V with current consumption up to 15 A.



The slats were deployed on both sides of the module. After one of the connectors is responsible for the control and power supply of the logical part. On the opposite side is the power contacts of the motor (V+, GND) and outputs (OUT, OUTB). The voltage value of the control signals must be in the range from 3.5 V to 5.5 V. the Manufacturer recommends does not work at the voltage of 3.3 V.


In a standard installation requires only the connection of the PWM signal and to a contact select the direction of motor rotation DIR. Flags FF1 and FF2 indicate incorrect operation of the system. Pin RESET to default selected to supply. When the status is restored low, the system will go into a state of minimal energy consumption. Will reset all flags.



Set includes

  • Driver module
  • Electrolytic capacitor
  • The bar goldpin
  • Connectors ARK


Insights driver Pololu


V+Motor power supply (5.5 V-30V). The conclusion is denoted by the symbol + is the positive pole connections of the capacitor. Less output V+ allows you to control the power of the engine. Not recommended for high currents.
5V (out)The output of the voltage regulator is 5V. The output current to a few mA. Be careful to avoid a short circuit with the adjacent terminal V+ as it leads to irreversible damage of the module.
GNDThe potential of mass of the system.



Insights for the DC motor.
PWMSignal speed control. Default in the low state
DIRThe choice of the direction of rotation of the motor. In the high state, the current flows from the output OUT to OUTB. By default, the floating state (float).
RESET After filing lowest position the system is in a low power state. Removes all the flags.



Status flags system. In the event of an error, the status is high.
