You need to make the serial programming interface of the Sonoff module / the ESP8266 microchip available. In most cases the pins are available on the PCB but connectors need to be soldered to allow interfacing. You'll furthermore need a **3.3V FTDI USB-to-Serial Converter/Programmer**.
### Attention ⚠️️⚠️️⚠️️

**Do not connect AC power and the serial connection at the same time**
Shorting your serial interface with AC will fry your module, programmer and even your PC.
If you are not careful, your own health might be in danger.
## Serial Connection

Pay attention to the fact, that RX and TX are crossed.
Some Sonoff modules expose a five pin header. The fifth pin is irrelevant for the serial connection. Please check the specific modules pages to find out more.
