00:00Fix Low Voltage with MT3608 Boost Converters
00:04So your project keeps dying at the weirdest moments, sensor reads 3.2 volts instead of 5,
00:09phone won't charge, Arduino board resets the second you plug in the motor.
00:13That's a voltage problem, and the fix is smaller than you think.
00:17I went through the listings and found the best deals on MT3608 Boost Converter Modules,
00:22and honestly some of these prices are almost too low to be true.
00:26Starting with the cheapest option, this MT3608 DC-DC Step-Up Converter with Type-C and Micro-USB
00:32inputs, adjustable output up to 28 volts at 2 amps. It's 35 cents. That's the price of a coffee,
00:40and for a board that takes a dead 1.5-volt cell and gives you a clean 5 volts, it's
00:45absurd value.
00:46Thousands of people have bought it, and it still holds a 4.8-star rating.
00:51Buy a handful.
00:53Now if you want the classic version with a proper potentiometer trimmer and the added assurance of
00:57brand name, this SX1308 MT3608 is the one. Same 2-24 volts in, up to 28 out, 2 amps,
01:06but it comes in at $3.31, roughly 10 times the price, and here's the thing, it doesn't feel 10
01:12times better. You get a solid, well-made module with a good-sized adjustment screw,
01:17which matters if you're fine-tuning voltage by feel. Worth it if you want one good board instead
01:22of a drawer full of mystery ones. Third option is the 5-pack of MT3608 adjustable boost modules at
01:2939 cents each, so under 2 bucks for the whole lot. Same 2-24-volt input range, and you can
01:35dial in 5,
01:369, 12, or 28 volts out. This one's for you if you have multiple builds going, or you're wiring up
01:43a
01:43bunch of LEDs, or you just plan to fry a few while learning. Learn on these, save the good ones
01:49for
01:49the final build. Then you've got the 10-pack at $6.04, and this is the deal for power users.
01:56Micro USB and Type-C plugs right on the board, adjustable from 2-24 volts in and 5-28 volts
02:03out,
02:032 amps. 10 of them for the price of 1 decent soldering iron. It's the highest rated of the
02:09whole bunch at 4.9 stars, which tells you people who bought 10 of them were happy.
02:14This is my pick if you tinkering is half your hobby.
02:18Alright, the links for all of these are in the description below.
