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. A Enable Pin (EN) is located on the board and can be used to switch the voltage converter on and off. If you want to keep the voltage converter always on, you must connect EN with VN+. This voltage converter module is therefore perfect for providing voltage to an ESP8266 or ESP32. For voltage stabilization, you can also connect a capacitor in parallel to the output.
