ขาย Motor Drive Shield dual L293D for arduino ราคาที่ดีที่สุด

Scope: beginners, experimental equipment platform, interactive electronics, robotics. Features: multi-function, easy to operate, have powerful drive library support and feature updates. Disadvantages: I / O occupy more drive Quad motor case (relative I / O less version), a small power. 4-channel DC motor drives, stepper motor or 2 while driving two servos, support for the latest UNO Mega 2560 You can mix: DC motor driver quad and two steering gear Drive two DC motor and stepper motor all the way and two-way steering gear Drive two stepper motors and two servos Is a good entry-electronic production, with motor expansion board can be a good robot development platform. Here a motor can drive a variety of simple to a slightly complex projects full function expansion board. This is a common DC motor drive module, 293D the chip small current DC motor driver chips. The pin is made of the Arduino compatible, but also facilitate enthusiasts based development. * 2 5V servo motor (Servo) port coupled to the high-resolution high-precision timer - no jitter! * Up to 4 bi-directional DC motor and 4-channel PWM speed (about 0.5% resolution) * Up to 2 stepper motor control, single / double step control, staggered or micro-step rotation angle control. * 4 H-bridge: the L293D chip to provide road and bridge .0.6 A (peak 1.2A) current and with a thermal power protection 4.5V to 36V. * The pull-down resistors guarantee on the electric motor remains stopped. * Large terminal terminals to make wiring easier (10 - 22AWG) and power. * With a reset button. * 2 large terminal external power terminals to ensure that logic and motor-driven power separation. * Compatible with Mega, Diecimila, & Duemilanove. * To provide a full range of spare parts available would like to do-it-yourself enthusiasts DIY. * Download the easy-to-use software libraries rapid project development
