4 — Channels Motor Shield

This Adru­ino com­pat­i­ble motor Dri­ver shield is a full-fea­tured prod­ucts that it can be used to dri­ve 4 DC motor or two 4‑wire step­per and two 5v ser­vo. It dri­ve the DC motor and step­per with the L293D,and it dri­ve the ser­vo with arduino pin9 and pin10.FeaturesBe able to dri­ve 4 DC motor and 2 ‘hop­py’ Ser­voBe able to dri­ve 2 step­per and 2 ‘hop­py’ Ser­voThe log­ic con­trol volt­age Vss: 4.5~5.5VMotor Sup­ply Volt­age: 4.5 ~ 12VReduced con­trol pins need­ed through 8‑stage ser­i­al shift reg­is­tersDri­ve part of the oper­at­ing cur­rent Io: 1.2AWiki & External linksManual&WikiMotor dri­ver Shield library(arduino_0022)Motor dri­ver Shield library(arduino_1.0)Schemat­ics and Lay­outL293D Datasheet74HC595 Datasheet
