아이폰 스피커 독 만들기 - 1. 기존의 스피커에 iPhone dock connector 달기
| Pin | Signal | Description |
| 1 | GND | Ground (-), internally connected with Pin 2 on iPod motherboard |
| 2 | GND | Audio & Video ground (-), internally connected with Pin 1 on iPod motherboard |
| 3 | Right | Line Out - R (+) (Audio output, right channel) |
| 4 | Left | Line Out - L(+) (Audio output, left channel) |
| 5 | Right In | Line In - R (+) |
| 6 | Left In | Line In - L (+) |
| 8 | Video Out | Composite video output (only when slideshow active on iPod Photo) |
| 9 | S-Video Chrominance output | for iPod Color, Photo only |
| 10 | S-Video Luminance output | for iPod Color, Photo only |
| 11 | GND | If connected to GND the iPhone sends audio signals through pin 3-4, otherwise it uses onboard speaker. |
| 12 | Tx | ipod sending line, Serial TxD |
| 13 | Rx | ipod receiving line, Serial RxD |
| 14 | RSVD | Reserved |
| 15 | GND | Ground (-), internally connected with pin 16 on iPod motherboard |
| 16 | GND | USB GND (-), internally connected with pin 15 on iPod motherboard |
| 17 | RSVD | Reserved |
| 18 | 3.3V | 3.3V Power (+) Stepped up to provide +5 VDC to USB on iPod Camera Connector. If iPod is put to sleep while Camera Connector is present, +5 VDC at this pin slowly drains back to 0 VDC. |
| 19,20 | +12V | Firewire Power 12 VDC (+) |
| 21 | Accessory Indicator/Serial enable | Different resistances indicate accessory type: |
| 22 | TPA (-) | FireWire Data TPA (-) |
| 23 | 5 VDC (+) | USB Power 5 VDC (+) |
| 24 | TPA (+) | FireWire Data TPA (+) |
| 25 | Data (-) | USB Data (-) |
| 26 | TPB (-) | FireWire Data TPB (-) |
| 27 | Data (+) | USB Data (+) iPod 5G can also be forced to charge by attaching the data + and the data - pins to the 5v via a 10k Ohm resistor ( BOTH PINS) and connecting pin 16 to the 5v (ground). (Confirmed working with iPod 5G 20GB) To charge an iPhone 3G / iPod Touch 2nd gen or Ipod Classic (6th Gen), usb data- (25) should be at 2.8v, usb data+(27) should be at 2.0v. This can be done with a few simple resistors: 33k to +5v (23) and 22k to gnd(16) to obtain 2v and 33k to +5v and 47k to gnd to obtain 2.8v. This is a notification to the iphone that it is connected to the external charger and may drain amps from the usb. To charge iPod Nano pins 25 and 27 should be tied together and then connected to a 10K ohm resistor, and the other side of this resistors then needs to be connected to 5v power. It's also possible to charge the iPod's or iPhone's battery to make use the of internal +3.3v output (18) terminal to connect the USB Data + (27) thru a 47k ohms resistor and the USB Data- (25) thru a 47k resistor to the USB Power source +5v (23). This way the USB function is still useable for normal operations and makes it easier the fit in a plug. The resistors are not to critical 2x 150k's still work. |
| 28 | TPB (+) | FireWire Data TPB (+) |
| 29,30 | GND | FireWire Ground (-) |
