171w ago - With the release of PSGroove opensource PS JailBreak exploit for PS3, many are having trouble sourcing the required Teensy++, AT90USBKEY2 or AT90USB162 boards.
That said, today PS3JailBreak.com (linked above) has shared schematics for the Teensy so that users can build their own if they wish.
As always, click on the picture below to enlarge it folks.
Finally, those who aren't into DIY solutions may also wish to look into either the AT90 USB thanks to Fuddster or the BlackcatUSB Flash Memory Programmer (from version 1.2 on) which uses the same microcontroller (AT90USB162) as confirmed by chesteruhi. More on that soon, including a video!
To quote: "The full schematics are available below (1.0 are on the top 2.0 are on the bottom)."
