S09 5V Step Up/Down Converter 3-15V to 5V 600mA

The S09 is a DC-DC voltage converter that automatically switches between step-up and step-down. From 3 V to 15 V, it generates a regulated 5 V with a maximum of 600 mA, and the quiescent current is below 200 µA. The module is suitable for powering an ESP8266 or ESP32, and a capacitor can also be connected in parallel at the output for stabilisation.

Recommended alternative with 3.3 V at the output: S09 3.3V Step Up/Down Converter 3-15V to 3.3V 600mA
