After a lengthy pause I have started playing with the ESP8266 modules again and I was getting annoyed by all the wires when using them on a bread board. So, like others before me, I built a small bread board adapter.
When building prototypes on breadboards I find it useful to have small pre-made components such as 3.5 stereo jack sockets configured to fit breadboards
The 3.5 stereo socket is attached to a small piece of board and the connectors from the socket attached to pins that fit in to a breadboard.
Red is VCC, black is ground, and white is the centre channel or data
