Dual Full-Bridge Driver L298N Here's an example of an Arduino "Shield" that plugs on top of an Arduino.This uses a motor driver chip L298N which we will detail more about later. Details of operation of the L298N Arduino Motor Driver Shield are HERE:Dual Full-Bridge Driver L298N The L298N is an integrated monolithic circuit in a 15-lead Multi watt and PowerSO20 packages. It is a high voltage, high current dual full-bridge driver designed to accept standard TTL logic levels and drive inductive loads such as relays, solenoids, DC and stepping motors. Two enable inputs are provided to enable or disable the device independently of the input signals. The emitters of the lower transistors of each bridge are connected together and the corresponding external terminal can be used for the connection of an external sensing resistor. An additional supply input is provided so that the logic works at a lower voltage. Stand-alone Motor Driver board This includes a heat sink for the L298N chip, allowing higher currents. It is also less expensive than a shield version. Often it can be mounted near the motorsL298N Here's the schematic diagram for that board:L298N
