Powering Two motors using LM2577 connected to a powerbank

Hello,

I am making a small toy car. I use a power bank USB 5-volt output to supply the car's two engines. The engines are relatively small and should not consume a large current. I need to increase the voltage to at least 7.2 or higher. Can I connect an LM2577 module to my power bank for a higher voltage? I want to use this module: Amazon.com: MT3608 DC-DC Converter, 2A 2V~24V Adjustable Voltage Step Up Module Power Supply Module 2A : Electronics

Please advise.

Best,
Eric

Please read and use this link: How to get the best out of this forum - Using Arduino / Project Guidance - Arduino Forum

Links to datasheet for the motors, the power bank and power converter.
Items being "similar" is not good as reference.

Assuming you have the correct parts, it should work fine. If not, you might encounter some serious issues.

It seems you want to use a boost converter to compensate for the voltage loss of a crappy L293/298 motor driver. If so, then using a more modern motor driver with mosfets could be a better solution. The TB6612 comes to mind.

Can you measure how much current they consume at 5V and 7.2V? Free-running and stalled?

Hello,

I tried the voltage step-up module, and it worked. Thanks for your replies.

Best,
