## Hardware Preparation
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 or otherwise applied to allow interfacing. You'll furthermore need a **USB UART TTL 3.3V Converter/Programmer** (e.g. CP2102, CH340G, FT232, PL2303).

Be careful - some so called 3V3 FTDI cables actually supply 5v on the VCC line. I suggest you measure before connecting to your Sonoff.
