This is the SparkFun RJ11 Breakout, two simple breakout boards for the common 6-pin RJ11 connector. These little boards can easily have one of our RJ11 6-Pin Connectors to work with common telephone cables. Each board features standard B/R/Y/G (Black/Red/Yellow/Green) labels on the top of the board to match a standard telephone wire. Additionally, each board has pin numbers on the back side that match the pins on the connector. Each breakout consists of two boards -- one for each end of the connections -- as well as mounting holes to help you secure your project in place.
