Scope: Arduino beginners, Arduino experiment equipment platform, Arduino interactive electronic, Arduino robotics. Features: multi-function, easy to operate, there is a strong drive library support and feature updates. Cons:
the case of I / O takes more while driving the four motors (as opposed
to Arduino I / O versions in terms of less), small power. You can drive 4 DC motors or 2-way stepper motor while driving two servos, support for the latest Arduino UNO, Arduino Mega 2560 You can match this:
four DC motor drive and two servo
drive two DC motors and stepper motor all the way and two-way servo
drive two stepper motors and two servos Arduino is a good electronic production started, with the motor expansion board can become a good robot development platform . Here one can drive a variety of simple to slightly more complex project full-featured motor expansion board.
This is a common DC motor drive module, using 293D chip low current DC motor driver chip. Pin is made of Arduino -compatible, but also convenient lovers fast Arduino-based development . * 2 5V servo motors (servo) port coupled to the Arduino's high-resolution high-precision timer - no jitter! * Up to 4-way and 4-way PWM DC motor speed (about 0.5% resolution) * Up to 2
stepper motor reversing control, single / double step control, staggered or micro-step and the rotation angle control.
* 4 H- bridge: L293D each bridge chip provides .0.6A (peak 1.2A) and with current thermal power protection, 4.5V to 36V.
* Ensure that the pull-down resistor on power motor remains stopped.
* Large terminal terminals make wiring easier (10 - 22AWG) and power supply.
* With Arduino reset button.
* 2 large terminal external power supply terminals and the motor drive power ensure logical separation.
* Compatible with Mega, Diecimila, & Duemilanove.
* Provide full set of parts for want-it-yourself enthusiast DIY.
* Download the easy to use Arduino software library rapid project development |
