This is the MT3608. It is a exact copy of the famus MT3608 board.

It is a DC-DC step up adjustable boost converter. It can take input voltages as low as 2V and step up the output to as high as 28V. The MT3608 features automatic shifting to pulse frequency modulation mode at light loads. It includes under-voltage lockout, current limiting, and thermal overload protection.

This module has a multiturn trimpot (potentiometer) that you can use to adjust the output voltage. Since the trimpot has 25 turns of adjustment you can easily adjust the output of the module to exactly the voltage you need.

Boost converters are a great way to easily increase a given voltage, but that boost comes at the cost of less output current compared to input current. Since this is a boost converter the output voltage has to be higher than the supplied input voltage.

I hope you have fun with it! ;)

There is not a potentiometer in the LCSC store, that matches the MT3608 potentiometer. You could use the C118925, just bend the pins, so it fits. In that case, be careful that the contacts fit the schematic or use somethin else. Anything that is a 100KΩ precision potentiometer should work.
Have fun!

I have used the famus MT8608 board and Arduino on a hardware-based project and it went pretty well. now I have a project delayed in the subject of MScD (Material, Semiconductor, and Diode). I have to create a project using Zener diode. I have asked for the help of cipd writers but couldn't satisfied. I need to do it on my own. As you have defined your project using simple diode and MT3608, and it is DC-DC. but I want to keep mine as DC-AC. Is it possible?

A current-mode setup-converter intended for small, low power applications. Its feature is that automatic shifting to pulse frequency modulation mode, My brother used this chipboard for making his little application programs, while I was just preparing low price dissertation in 7$ for my students.
