Description

Very Small DC-DC Buck-Boost Converter

The idea to create the DC-DC Buck-Boost converter came when i had not found ready to use small modules that can boost and buck input voltage to 3.3V. That is why I decided to create my module that can be used to provide proper voltage for STM32, ESP32, Arduino microcontrollers or others with high efficiency (up to app. 94%) and operates with 1.8-5.5V input (Li-Ion/Li-Pol Battery, USB and others). It has dimensions 16.9x26 mm (like TP4056 Charging module) and can be hidden in the box of your own project
