In this project I will try to remake an AliExpress PCB. It is a very handy voltage converter that can take a varying battery voltage and convert it into 3.3V or 5V while only requiring very little current (25uA) on the input. Sounds awesome, but the board is way too huge. That is why I try to push the size limits in this video to the minimum. Will I succeed?? Let's find out!
