Pololu Motor Controllers

Introduction

Ideal for small autonomous robots that do not require a RC (radio control) input as well as the TRex controllers that are ideal for RC robots. We also stock the Pololu range of Orangutan robot controllers which combine motor controllers and a programmable microcontroller.

Pololu Dual Serial Motor Controller - Part No: 1503-003
The Pololu dual serial motor controller allows you to control two DC motors with almost any microcontroller. Using one serial output from your microcontroller, you can independently set each motor to go forward or backward at any of 127 speeds.

Pololu Micro Dual Serial Motor Controller - Part No: 1503-001
Pololu's popular micro motor controller will get your robot running in a snap. The tiny module can individually control two motors, and you can daisy-chain multiple units to control up to 62 motors with one serial line. The new version provides up to 2 A to a single motor, or 1 A each to two motors. The motor supply can be as low as 2 V, {} Making the unit a perfect match for small DC motors.

Pololu Micro Dual Serial Motor Controller

Pololu Low-Voltage Dual Serial Motor Controller - Part No: 1503-002
This low-voltage version is designed specifically for high-performance, low-voltage motors that run on 1.5 - 6 V. Because they run at lower voltages, these motors have higher current requirements, making them difficult to control since most integrated motor drivers are designed either for low-current, low voltage motors (such as those in CD players or cameras) or for higher-voltage motors that run at 6 volts or more. With this latest motor controller, you can consider a whole new range of motors for your next high-performance robot.

Pololu Low-Voltage Dual Serial Motor Controller

Pololu 3A Motor Controller with Feedback - Part No: 1503-004
The 3-Amp motor controller with multiple interface and feedback options simplifies servo control of commonly available DC motors. The module features three independent interfaces: a serial protocol for microcontroller-based applications, a pulse-width interface for connection to hobby radio control equipment or serial servo controllers, and an analog voltage interface for simple tests and demonstrations. Two feedback alternatives allows for closed-loop control of position or speed.

Pololu SMC04 High Power with Feedback - Part No: 1503-006
The SMC04 high-power motor controller with feedback has multiple interface and feedback options that simplify servo control of commonly available DC motors. The module features three independent interfaces: a serial protocol for microcontroller-based applications, a pulse-width interface for connection to hobby radio control equipment or serial servo controllers, and an analog voltage interface for simple tests and demonstrations. Two feedback alternatives allows for closed-loop control of position or speed. The SMC04 is higher-current version of our 3A Controller with feedback which can handle larger motors with its VNH3SP30 motor driver chip (see also our 30A driver board.

1. Pololu 30A Dual Motor Driver VNH3SP30 (Ref: 1503-009)

Pololu 30A Motor Driver VNH3SP30 - Part No: 1503-007
The Pololu high-power motor drivers are compact carriers for the VNH3SP30 and VNH2SP30 (see 1503-008 below) motor driver integrated circuits from ST. The board incorporates most of the components of the typical application diagram on page 8 of the VNH2SP30 datasheet, including pull-up and current-limiting resistors and a FET for reverse battery protection. (The current sense circuit is populated on both versions of the board, but only the VNH2SP30 supports current sense.) All you need to add is a microcontroller or other control circuit to turn the H-Bridge on and off. If you need a full motor control solution, we also have a high power with feedback version (see 1503-006 above) that uses the same chips.
In a typical application, the motor power supply is connected at the bottom of the board, the motor on the right side of the board, and the control connections to the left side of the board. The diagnostic pins can be left disconnected if you do not want to monitor the fault conditions of the motor driver chip. INA and INB control the direction of the motor, and the PWM pin turns the motor on or off. For the VNH2SP30 version, the current sense (CS) pin will output approximately 0.13 volts per amp of output current.

Pololu 30A Dual Motor Driver VNH3SP30 - Part No: 1503-009
The Pololu dual high-power motor driver VNH3SP30 is a dual version of the 1503-007 above. As with the 1503-007, this dual version incorporates most of the components of the typical application diagram on page 8 of the VNH2SP30 datasheet, including pull-up and current-limiting resistors and a FET for reverse battery protection. (Again the current sense circuit is populated on both versions of the board, but only the VNH2SP30 (see 1503-010 below) supports current sense.) To keep the number of I/O lines down, the two enable/diagnostic lines on each chip are tied together. All you need to add is a microcontroller or other control circuit to turn the H-Bridges on and off.

Pololu Trex Jr Dual Motor Controller - Part No: 1503-015
A novel blend of serial, RC, and analog motor control:

The TReX Jr Dual Motor Controller, a lower-power version of the TReX Dual Motor Controller, is a versatile DC motor controller designed to seamlessly blend autonomous and human control of small robots. The TReX Jr can control two bidirectional and one unidirectional motor via three independent control interfaces: radio control (RC) servo pulses, analog voltage, and asynchronous serial (RS-232 or TTL). Using the compact MC33887 motor driver allows for a single-board design that reduces cost while maintaining a small package. As an added benefit, the use of the MC33887 motor driver allows operation to 24 V.
