Stepper Motor Driver Dual H Bridge L298N

This module uses ST L298N dual full-bridge driver, an integrated monolithic circuit in a 15-lead Multiwatt and PowerSO20 packages. It is a high voltage, high current dual full-bridge driver designed to accept standard TTL logic levels and drive inductive loads such as relays, solenoids, DC and stepping motors. Two enable inputs are provided to enable or disable the device independently of the input signals. The emitters of the lower transistors of each bridge are connected together, and the corresponding external terminal can be used for the connection of an external sensing resistor. An additional supply input is provided so that the logic works at a lower voltage.

Stepper Motor Driver VNH2SP30

Drive up to 30A(max)/14A(continuous) with this dual H bridge motor driver. When using this board in extreme high-demand applications it may be necessary to improve thermal performance with a heat-sink or fan. However, when using the board at currents up to 6A the chips will barely become noticeably warm. This driver features Thermal Shutdown and Undervoltage/Overvoltage shutdown.

Stepper Motor Driver EasyDriver

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). EasyDriver requires a 7V 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! EasyDriver drives bi-polar motors, and motors wired as bi-polar. I.E. 4, 6, or 8 wire stepper motors. On this version (v4.4) we fixed the silk error on the min/max adjustment.

Motor Driver 9 - 36v 15A

This is a H-bridge module gate circuit, motor reversing combination with MOS transistors, braking and speed control. Motor control can be powered and driven with both 3.3v and 5v. Control signals are isolated via optocouplers. Built in power supression to counter voltage spike.

Servo Motor Driver PWM 16 Channel 12-Bit PCA9685

If you are running short of PWM pins, this is the solution for you. Driving with only 2 pins, you can get up to 16 channels of 12-bit PWM outputs! It's an I2C controlled PWM driver with a built in clock. That means that, unlike the TLC5940 family, you do not need to continuously send it signal tying up your microcontroller, its completely free running!

Stepper Motor 2-Phase Driver TB6600

This is a bipolar constant current chopper. Signal is isolated via a high-speed optocoupler, electrical input signal is TTL compatible and stationary current is automatically reduced by half. Suitable for any small/medium automatic equipment with CNC controller, such as X-Y-Z tables, labeling machines, laser cutters, engraving machines, and pick-place devices.

Stepper Motor Driver Dual H Bridge L293D

This is a monolithic integrated high voltage, high current four channel driver designed to accept standard DTL or TTL logic levels and drive inductive loads (solenoids, DC motors, stepper motors) and switching power transistors. To simply use as two bridges, each pair of channel is equipped with an enable input. A separate supply input is provided for the logic, allowing operation at a lower voltage and internal clamp diodes are included. This device is suitable for use in switching applications at frequencies up to 5 kHz.
