Product description
This shield makes it easy to control two brushed DC motors with your Arduino or Arduino-compatible board. Its dual TB9051FTG motor drivers operate from 4.5 to 28 V and can deliver a continuous 2.6 A per motor (5 A peak). These great drivers also offer current-sense feedback and accept ultrasonic PWM frequencies for quieter operation. A fixed current chopping threshold allows each TB9051 to limit the peak motor current, and they feature built-in protection against under-voltage, over-current, and over-temperature conditions; our shield also adds reverse-voltage protection. The Arduino pin mappings can all be customized if the defaults are not convenient, and the motor driver control lines are broken out along the left side of the shield for general-purpose use without an Arduino.
This versatile motor driver is intended for a wide range of users, from beginners who just want a plug-and-play motor control solution for their Arduinos (and are okay with a little soldering) to more advanced users who want a general-purpose dual-channel version of our single-channel TB9051FTG carrier to use with other microcontroller boards, outside of the Arduino environment. The Arduino pin mappings can all be customized if the defaults are not convenient, and the simplified TB9051FTG control lines are broken out along the left side of the board, providing a convenient interface point for other microcontroller boards. This versatility, along with an option to power the Arduino from the shield, either directly or through an added regulator, sets this board apart from similar competing motor shields.
* Dual-channel H-bridge motor driver in the form factor of an Arduino shield
* Wide operating voltage range: 4.5 V to 28 V
* Output current: up to 2.6 A continuous (5 A peak) per motor
* Automatic current chopping feature helps prevent overheating by gracefully reducing power rather than abruptly shutting down
* PWM operation up to 20 kHz, which is ultrasonic and allows for quieter motor operation
* Current sense voltage output proportional to motor current (approx. 500 mV/A; only active while H-bridge is driving)
* Motor indicator LEDs show what the outputs are doing even when no motor is connected
* Can be used with an Arduino or Arduino-compatible board (through the stackable shield headers) or with other microcontroller boards (through the 0.1" header along the left side)
* When used as a shield, the motor power supply can optionally be used to power the Arduino base as well, either directly or through an added regulator like the D24V5F9 or S10V3F9
* Arduino pin mappings can be customized if the default mappings are not convenient
* Arduino library makes it easy to get started using this board as a motor driver shield
* Secondary access points for most Arduino pins, all on the same 0.1" grid
* Exposed solderable ground pad below each driver IC on the bottom of the PCB
* Reverse-voltage protection on motor supply
* Transient operation (< 500 ms) up to 40 V
* Under-voltage lockout and protection against over-current/short-circuit and over-temperature
* Active-low error outputs indicate over-current, over-temperature, under-voltage, or VCC over-voltage conditions for each driver
* Detailed user's guide
