Product Features:

  • L293D Motor Control Expansion Board Motor Drive Shield
  • Here is a design for a full-featured motor shield that will be able to power many simple to medium-complexity projects.
  • L293D is a monolithic integrated, high voltage, high current, 4-channel driver.
  • Basically this means using this chip you can use DC motors and power supplies of up to 36 Volts, thats some pretty big motors and the chip can supply a maximum current of 600mA per channel, the L293D chip is also what’s known as a type of H-Bridge.
  • The H-Bridge is typically an electrical circuit that enables a voltage to be applied across a load in either direction to an output, e.g. motor.
  • L293D Motor Control Expansion Board Motor Drive Shield Function:
  • --- 2 connections for 5V servos motor connected to the Arduino's high-resolution dedicated timer - no jitter!
  • --- 4 H-Bridges: L293D chipset provides 0.6A per bridge (1.2A peak) with thermal shutdown protection, internal kickback protection diodes. Can run motors on 4.5VDC to 25VDC.
  • --- Up to 4 bi-directional DC motors with individual 8-bit speed selection (so, about 0.5% resolution).
  • --- Up to 2 stepper motors (unipolar or bipolar) with single coil, double coil or interleaved stepping.
  • --- Pull down resistors keep motors disabled during power-up.
  • --- Big terminal block connectors to easily hook up wires (18-26AWG) and power Arduino reset button brought up top.
  • --- 2-pin terminal block and jumper to connect external power, for separate logic/motor supplies.
  • Forum link:
  • Tested compatible with Arduino Mega 1280 & 2560, Diecimila, Duemilanove, and UNO.
  • Color:as show in the picture

Cette carte controleur pour tout type de moteurs est géniale (c'est la première version de Adafruit (qui commercialise des V2 à prés de 30€).
Une trés bonne affaire.

Involvement: Expertos (comprende el funcionamiento interno) Ownership: Menos de 1 Semana

Pros: Compre este puenta H y es de excelente calidad y a un precio costo,
compre varios y funcionan perfectamente hasta ahora

Cons: Hasta la fecha no he detectado problema alguno

Other: La compañia Tinydeal la recomiendo por que he comprado varias veces y
nunca me han dejado de enviar algun producto, solo deben mejorar sus
tiempos de envio, sobre todo cuando uno paga por el servicio expreso
como DHL tardan varios días en enviar el producto, pero en general son
bastante buenos

Bottomline: Recomiendo el producto
