• Please see the E3x0/X3x0 GPIO API for information on configuring and using the GPIO bus.

Audio

The E3x0 2.5 mm Audio Jack TRRS pins are assigned as follows: Tip=Mic, Ring1=Right, Ring2=Left, Sleeve=GND. The Left/Right audio outputs are compatible with typical low-impedance headphones (16 to 32 Ohms). The Microphone pin provides approximately 2 mA bias at 2.2 V when not suspended. A variety of pin configurations can be found on commonly available headsets, so an adapter may be required.
