00:00Fix Motor Vibration Noise with PWM Driver Modules 7 Paragraph VO Script
00:05That awful grinding buzz coming from your motor? Nobody has to live with it. PWM lets you set the
00:13speed instead of running wide open, and the line disappears with it. I went through the top sellers
00:19so you don't have to. Here are the best deals I found for fixing motor vibration noise with PWM
00:25Driver Modules. First up is the adjustable speed controller that covers 1.8V all the way to 12V,
00:31so it fits basically anything with brushes in it. Small board, thumbwoofer speed, and around $3 for
00:38the one that's sold over 4,000 times. At $3, it's the cheapest way to kill that wine on a
00:43fan or a
00:44small DC motor. No code, no fuss. This MX1508 module is the one I'd actually buy. Dual H-bridge,
00:531.5A per channel, PWM speed control, and it can also drive a stepper. But the real reason it made
01:01the list is the price, $0.25 for a single board. That's less than a coffee. Buy 5 or 10
01:07of them
01:08for a project and you'll barely think about it. Same board, bigger bundle. This one's the 4-pack
01:14or 10-pack of MX1508 modules, around $4.24 for the lot. Why pay per board shipping when you can
01:21have spares on hand? If you're building a robot with four wheels, this is the pack. Buy one of
01:28these and skip the singles entirely. Then there's the Mini L298N, proper dual H-bridge, 1.5A, 2V-10V,
01:36with PWM input for smooth speed changes. This one sells as a ready-to-go Arduino and smart car
01:42module, so headers are already soldered and it drops right into a breadboard. 3.13 for that
01:48convenience is a fair trade if you'd rather not do the wiring. Note, pricing quoted as listed,
01:54$0.25 for single MX1508, $4.24 for 4-tenths pack.
