Availability: Stocked
Sparkfun Item #: ROB-12779 -

"The EasyDriver is a simple to use stepper motor driver, compatible with anything that can output a digital 0 to 5V pulse (or 0 to 3.3V pulse if you solder SJ2 closed on the EasyDriver). The EasyDriver requires a 6V to 30V supply to power the motor and can power any voltage of stepper motor. The EasyDriver has an on board voltage regulator for the digital interface that can be set to 5V or 3.3V. Connect a 4-wire stepper motor and a microcontroller and you’ve got precision motor control!...

SparkFun Motor Driver - Dual TB6612FNG (1A)
Price: $14.92
View
Availability: Stocked
Sparkfun Item #: ROB-09457 -

"The TB6612FNG motor driver can control up to two DC motors at a constant current of 1.2A (3.2A peak). Two input signals (IN1 and IN2) can be used to control the motor in one of four function modes - CW, CCW, short-brake, and stop. The two motor outputs (A and B) can be separately controlled, the speed of each motor is controlled via a PWM input signal with a frequency up to 100kHz. The STBY pin should be pulled high to take the motor out of standby mode. Logic supply voltage (VCC) can be in...

Pushbutton Power Switch LV

Availability: Stocked-NoBackOrder
Sparkfun Item #: ROB-08903 -

"The Pololu Pushbutton Power Switch from Pololu is a compact, solid-state power switch controlled by a momentary pushbutton switch. Because the switched current does not flow through the mechanical switch, a large variety of small, low-power switches can be used to control a substantial amount of power. The use of momentary pushbutton switches also allows multiple switches to be used in parallel to control the power to one load. The solid-state switch also allows the load to turn off its own...

Sparkfun Item #: ROB-09664 -

"The Micro Maestro is the first of Pololu’s second-generation USB servo controllers. The board supports three control methods — USB for direct connection to a PC, TTL serial for use with embedded systems, and internal scripting for self-contained, host controller-free applications — and channels that can be configured as servo outputs for use with radio control (RC) servos or electronic speed controls (ESCs), digital outputs, or analog inputs. The Micro Maestro is a highly...

Sparkfun Item #: ROB-09107 -

"The Pololu 15 Amp high-power motor driver is a discrete MOSFET H-bridge designed to drive one DC brushed motor. The H-bridge is made up of one N-channel MOSFET per leg, and most of the board’s performance is determined by these MOSFETs (the rest of the board contains the circuitry to take user inputs and control the MOSFETs). The board supports a wide 5.5 to 24 V voltage range and is efficient enough to deliver a continuous 15 A without a heat sink, or 21 A with a heat sink. With the...

SparkFun Ardumoto - Motor Driver Shield

Availability: Stocked-NoBackOrder
Sparkfun Item #: DEV-09815 -

"This is a motor shield for Arduino that will control two DC motors. Based on the L298 H-bridge, the SparkFun Ardumoto can drive up to 2 amps per channel. The board takes its power from the same Vin line as the Arduino board, includes blue and yellow LEDs to indicate active direction, and all driver lines are diode protected from back EMF. The new version of this shield allows for either 3.3 or 5v logic, a separate and more robust VIN connection, and the PWM input has moved to pin 3. Control...

Sparkfun Item #: DEV-14129 -

"The Ardumoto Shield is a dual-motor controller for Arduino. Based on the L298 H-bridge, the SparkFun Ardumoto can drive two DC motors up to 2A per channel. Combined with an Arduino, the Ardumoto makes a fantastic controller platform for RC vehicles or even small autonomous robots. It’s now easier to use, featuring control signal LEDs, while also being much more flexible for advanced users. The board takes its power from the same Vin line as the Arduino board and includes blue and yellow...

Sparkfun Item #: DEV-10182 -

"This is essentially a ramped up version of our Ardumoto motor driver shield. For this SparkFun Monster Moto Shield we’ve replaced the L298 H-bridge with a pair of VNH2SP30 full-bridge motor drivers. We’ve also beefed up the support circuitry so this board is capable of driving a pair of high-current motors! The VIN and motor out are pitched for our 5mm screw terminals (not included), making it easy to connect larger gauge wires. Note: When using this board in extreme high-demand...
