For a poor newbie/student with low or no income, learning all about basic things of a DC motor driver, (including theory and physical appearance of heat sink, flyback diodes, 7805 voltage regulator, speed feedback control using current sensor, etc etc), I think L298N module is the most time efficient, and of course the most *cost effective. In other words, it is the best!. | |

| Mar 27, 2021 at 15:03 | comment | added | Marcus Müller | this sounds like a very bad idea: instead of parallelling three 1970s, very inefficient (since high-loss) motor controllers, why not simply spend a fraction of the money on something modern? If L298N is the answer, then the question started with "Let's book time travel to the year 1978..." | |
| Mar 27, 2021 at 15:01 | comment | added | Tausif | This is just a rough thought. Instead of asking just a question in plain text, I thought I should make a rough diagram of what I'm trying to do to better explain things. I'm definitely not going to run 5A through a breadboard. Was just curious if stacking L298Ns in parallel to increase current output was possible or not. | |
| Mar 27, 2021 at 14:55 | comment | added | Spehro 'speff' Pefhany | You could probably bolt them to a common heatsink (so as they heat due to their horrible performance they more-or-less heat together) and get a slight (maybe 30-50%) improvement in output current, but they are really horrible parts. Did I mention they are horrible? | |
| Mar 27, 2021 at 14:53 | comment | added | Hearth | you should probably not be running the current for motors through breadboard traces. | |
| Mar 27, 2021 at 14:52 | comment | added | Transistor | Tip: the illustration you have posted is referred to here as a "cartoon" or wiring diagram. A schematic diagram reveals the schema or purpose of the circuit with part numbers and pin designations and is the "language" of circuits. Meanwhile your diagram shows us that you have a breadboard, two motors, an Arduino, a red PCB and a green thing. Most of the cartoon generators have schematic export functions although you will need to spend some time laying out the components sensibly and untangling the mess of wires they generate. | |
