Many functions, easy to operate, a powerful driver library support and function update. Product Arduino is a good introduction to electronic production. With the motor expansion board, Arduino can be a good platform for robot development. This paper introduces a full - function motor expansion board that can drive a variety of simple to slightly complex projects. This is a commonly used DC motor drive module, using 293D chip small current DC motor drive chip. The pins are made Arduino-compatible, which also facilitates fast Arduino-based development by hobbyists. 2 5V servo motor (steering gear) ports connect to Arduino's high resolution high precision timer - no jitter! Up to 4 bidirectional DC motors and 4 PWM speed controls (approx. 0.5% resolution) Up to 2 stepper motors for positive and negative control, single/double step control, staggered or microstep and rotation Angle control. 4-way H-bridge: The L293D chip provides.0.6A (peak 1.2A) current per bridge with thermal power off protection, 4.5V to 36V. The pull-down resistance ensures that the motor remains in a stopped state when powered on. Large terminal wiring terminals make wiring easier (10-22 AWg) and power. With Arduino reset button. 2 large terminal external power terminals to ensure the separation of logic and motor drive power. Compatible with Mega, Diecimila, & Duemilanove. A full set of pieces are available for enthusiasts who want to do it themselves. Download the easy to use Arduino software library for quick project development
