If you aren't planning to use the video output abilities, you can use 4 wires. We will use red for the +5V pin, black for the Ground pin, white for the RX pin (data into the module) and green for the TX pin (data from the module)
- Red is connected to +5V in
- Black is connected to Ground
- Green is RX
- White is TX
- Yellow is NTSC Video signal out
- Brown is NTSC Video ground
