The Polulu HP Motor Driver (24v12) 12 A is a powerful motor driver. The motor driver is a self-contained MOSFET H-bridge designed to drive large DC motors. The HP motor driver consists of one N-channel MOSFET per leg. Most of the board performance is determined by the MOSFETs. The rest of the board contains the circuit to make user inputs and control the MOSFETs. The MOSFET datasheet can be found here. The absolute maximum voltage of the HP Motor-Driver is 40 V. Please note that a permanently higher voltage can destroy the motor driver. Under normal operating conditions, the ripple voltage on the supply line can raise the maximum voltage to more than the average or expected voltage. A safe voltage is about 34 V.

PIN ground state Description
V+ This is the 5.5 to 30 V (absolute maximum) main motor power supply connection that should typically run to the larger V+ pad. The smaller V+ pads along the long side of the board are for power supply capacitors, and the smaller V+ pads on the logic side give you access to monitor the motor power supply (it should not be used for higher currents).
5 V (out) This regulated 5 V output offers several milliamps. Can be shorted to VCS to drive the current sensor. This output should not be connected to other external power supply lines. Please be careful not to inadvertently short-circuit this pin to the adjacent V+ while power is being supplied. If this happens, the board will be immediately destroyed!
VCS This pole connects to 5 V to drive the current sensor.
GND Ground connection for logic circuit and power supply
CS On CS714 Current Sensor Output (66 mV/A centered at 2.5 V)
OUTA A Motor output
OUTB B Motor output
PWMH LOW Pulse width modulation input: a PWM signal on this pole corresponds to the PWM output on the motor output
PWML HIGH control input which allows deceleration operation when both PWML and PWMH poles are set low.
DIR LOW Direction input: when the pole is set high, the current flows from OUTA to OUTB. When the pole is set to low, the current flows from OUTB to OUTA.
RESET HIGH The RESET pole is pulled up to the V+ pole by a 20 kilo-ohm resistor. When the pole RESET is kept low, the driver switches to a low power consumption sleep mode and loses any permanent error flags.
FF1 LOW Error flag 1 Indicator: This pole is set to high when certain errors occur.
FF2 LOW Error flag 2 Indicator: This pole sets to high when certain errors occur.
