The Idea
We as a maker frequently work with multiple voltages and we all love the popular Lithium-Ion Cells/Batteries. We work with Microcontrollers (Eg: ESP MCUs) that work on 3.3v and some popular development boards like Raspberry Pi Pico, Arduino UNO, Arduino Nano, etc. Some discrete projects need 1.8V and some projects need 12V as the power supply.

We face the challenge of varying the voltage and sometimes we consider alternate boards for alternate voltages. A popular boost module on MT3608 acts friendly for us but it uses a potentiometer to vary the voltage, then we have to hot glue the pot and use it with a fixed voltage.

To solve this dilemma, We thought of modifying the electronics and making them precise with the popular voltage outputs only. We decided to use the most modern tech on this project with core components.
