L298 18V, 2A Dual Stepper Motor / Quad DC Motor Driver

Introduction

L298 18V, 2A Dual Stepper Motor / Quad DC Motor Driver module from NEX Robotics can drive two bipolar stepper motors or 4 DC motors at the same time. Board has two L298 motor driver ICs. Each L298 has two H-Bridges. Each H-Bridge can supply 2Amp. current. Board has onboard 5V low drop voltage regulator for generating logic supply. Each L298 has heat sink for better heat dissipation, flyback diodes for protection from back EMF and current sensing resistor for current sensing. For higher current rating these H-Bridges can be connected in parallel. Board has 20 pin FRC connectors for logic interfacing and terminal blocks for power and motor interfacing. In the minimal configuration only one FRC connector needs to be used. Second FRC connector is used for enhanced features such as current sensing, H-Bridge enable etc. Board is made of double sided PTH PCB for giving better strength to the connectors. Two LEDs are connected across each H-Bridge for easier debugging. For easier mounting board have six mounting holes.
