L298N: Dual Full-Bridge Driver
Darlington Transistor Arrays Based — 3A@50v peak — Ardu-Serie#52
Goal: run two 12v 350 RPM motors on one L298N Driver. These motors are part of my project Meet J3C3 — Assembly Techniques — J3 Caterpillar-Crawler-Chassis v 1.0 — ArduSerie#46
The L298 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.
Here is my first attempt:
And here is my second Attempt:
The Only Consideration About This Module
The great concern of this module has a relation with the 5v jumper (JP1).
If you use motors below 12v, keep the jumper and 5v will be output and the internal circuits will be fed by the 5v regulator. That was my approach to the primary lab above:)
If you use motors above 12v, remove the jumper; with that, you disable the 5v regulator, the corresponding pin will be input and you need to feed the internal circuit with 5v. That was my approach to the secondary lab below;)
That’s it!
