2012년 글에서는 I2S가 사라졌다고 하는데
리비전 2 부터는 P5 헤더에 존재하게 되엇다는데 끄응..
라즈베리 2에서 안되는거 같기도 하고... 미지수네
Moderator: this is an old thread! Since revision 2 the PI has a new header P5 which has I2S.

- P1: 26-pin (2x13) 2.54 mm header expansion, providing: see Low-level peripherals
- 8 GPIOs at 3v3
- 2-pin UART serial console, 3v3 TTL (debug); or 2 GPIOs at 3v3
- I²C interface (3v3); or 2 GPIOs at 3v3
- SPI interface (3v3); or 5 GPIOs at 3v3
- 3v3, 5v and GND supply pins
- ARM JTAG (if pins are reconfigured in software - on Revision1.0 boards one signal would also need to be taken from S5)
- I²S interface (if pins are reconfigured in software, hardware hack may be required[4])
- P2: 8-pin 2.54 mm header expansion (header not fitted on Revision 2.0 boards), providing GPU JTAG (ARM11 pinout, pin 7 is nofit for locating)
- P3: 7-pin 2.54 mm header expansion (header not fitted), providing LAN9512 JTAG (pin 6 is nofit for locating)
- P4: 10/100Mb RJ45 Ethernet jack (Model B)
- P5: 8-pin (2x4) 2.54 mm header expansion (header not fitted), on the bottom of the board, providing: see Low-level peripherals (Model B Revision 2.0 and Model A boards only)
- 4 GPIOs at 3v3
- 3v3, 5v and GND supply pins
- Second I²C interface (3v3) (if pins are reconfigured in software)
- I²S interface (if pins are reconfigured in software)
- Handshake signals for the UART on the P1 header (if pins are reconfigured in software)
- P6: 2-pin 2.54 mm header expansion (header not fitted), providing an option to connect a hardware-reset button (Revision 2.0 boards only)
