PSP Go Cradle, mini USB Tutorial, with Partial Pinout

[Nanaki666]

Here's some details to add a Mini-USB to your PSP Go cradle. Check the pictures for more details.

Mini-USB pinout:
1- +5V
2- D-
3- D+
(4)5- GND

PSP Go Pinout (related to USB):
1: GND (Ground can be found anywhere on the board)
2: D+
3: D-
4: GND (Ground can be found anywhere on the board)
8: +5V USB

You can solder the shield and the ground directly on the board from the mini-usb, between the power jack and the PSP go connector.
You will need to remove some plastic on the top part for the box to close.

------------------------------------------------

You can add a 3.5mm connector (audio) to plug your headphones or external speakers. You will need a connector that provide GND on a pin when something is plugged in. Or you can Connect the "Ena. Audio" pin to Ground but that way no sound will ever come out of your PSP when it's on the cradle.

PSP Go Pinout (related to Audio):
19: Enable Audio Out (when Grounded)
20: GND (Ground can be found anywhere on the board)
21: Right
22: GND (Ground can be found anywhere on the board)
24: Left

------------------------------------------------

Here's the rest of my findings (thanks to Sisee for the component part). But i'm not able to switch my PSP to Video Out, if someone can help me ^^

1: GND
2: D+
3: D-
4: GND
5: ???
6: ???
7: +5V (Not from USB)
8: +5V USB
9: ???
10: Component Blue
11: ???
12: GND
13: Component Green
14: ???
15: Enable Component Video Out
     (Resistance 50k to GND)
16: Component Red
17: GND
18: GND
19: Enable Audio Out (when Grounded)
20: GND
21: Right
22: GND
23: ???
24: Left
25: ???
26: ???
27: ???
28: GND


Have fun

for the jack issue why not just put a switch on the cradle and set it up to where you can chose between audio out/psp

[Nanaki666]

You can do that too !

hmm... I wonder if you solder some LED's to the sound then would it be sound reactive? that make a cool jukebox LOL

[Nanaki666]

If you activate the audio out then no sound will come out of the psp and if you don't activate it then no sound come out of the pins.
But if you have external speakers then yeah the leds will react.

Is the pinout you have for the cradle the same as the plug for the actual PSP - Curious b/c I am looking to do an internal camera mod and needed the pis for the USB .. Thanks

[Nanaki666]

Yes It's the same but I don't think that the usb pins are the same for the cam. (Host vs Device). But it's possible that the Pins 25 and 27 are the D+ and D- for the ext. usb devices.
If it's working please tell me I will Update my pinouts

My cheap component cable had 220uF capacitors in series of Pr/Y/Pb lines. (With - side towards the cinch plug center)
Of course: Y = green plug, Pb = blue plug, Pr = red plug.
As for the resistor for video, I measured 42k instead of 50k (but not sure if the battery in my multimeter was ok).
I want to add USB power to it, so I guess I have to crack open the connector somehow.
Hopefully the audio will be undistorted. (I had an issue with my iPhone component cable.)
Or perhaps I just should buy a cradle and use PS3 controller. Or just use my PS3... hmmm

great post!
It is possible to do that directly to the mainboard? to be able to charge the battery?, my Psp go has the pins broken. THNKS!!!!

great post!
It is possible to get great results with creatine and do that directly to the mainboard? to be able to charge the battery?, my Psp go has the pins broken. THNKS!!!!

How do you do that?
