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

The S09 is a DC-DC voltage converter that can automatically switch between Step-UP (boost converter) and Step-Down (buck converter). The maximum input voltage is 15VDC, the quiescent current is less than 200uA. The regulated output voltage is 5V and the maximum output current is 600mA. The board features an Enable Pin (EN) with which you can turn the voltage converter on and off. If you want to always turn on the voltage converter, you must connect EN with VN+. This voltage converter module is therefore perfect for powering an ESP8266 or ESP32. For voltage stabilization, you can also additionally connect a capacitor in parallel to the output.
