Miniature boost converter with 5V/600mA output ideal for powering sensors (air quality) or addressable RGB LED strips from a flashlight and functioning as a switch.
On the 15.3 x 10.2 mm board is a DIO6605 switching circuit operating at 1.2 MHz. With such a small board you are able to power devices with 5V input voltage and up to 600mA.
And it also acts as a switch. The EN pin has its own pin for controlling the inverter and also a solder bridge if you don't want to worry about switching and the inverter can run. If EN is connected to VIN (or the voltage is higher than 1.6V - for example from ESP8266/ESP32/RaspberryPi), the inverter is on. If the voltage is lower than 0.4V, it is in the off state and thus draws less than 1uA ! At the same time, of course, the device that is powered from the inverter is also switched off.
