Hey DIY electronics folks, this is a super handy pack of 10 boost converter modules. What do they do? They take a lower DC voltage (anywhere from 2V to 24V) and 'boost' it up to a higher voltage you can select (from 5V up to 28V, but it's best to keep it under 26V). The max output current is 2A, and efficiency can be as high as 93%.
The cool feature is the dual input: you can power it via the solder pads OR through a Micro USB port. That means you can use a common phone charger or power bank with a USB cable to get stable 9V, 12V, etc. – super convenient! It's based on the MT3608 chip and has built-in protection against overload, short-circuits, and overheating. Each module is tiny (about 1.2\ x 0.7\). Perfect for powering projects, making adjustable bench supplies, or boosting battery voltage.
