This board breaks out the all the pins you will need to gain access to your TRS jack including GND, T (tip), TN (tip neutral), R (ring), RN (ring neutral), S (sleeve), and SN (sleeve neutral). Weve also included two mounting holes, which can easily be snapped off if need be, for your basic 4-40 type screw.
