September 2, 2010 // 1:52 am - 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 (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)."

Electronics experts, if we print and build the teensy pcb do i need to flash the bootloader or its preinstalled ? I know haveI to load the hex later on, but will the pcb fuction as it should ?

Please I need to know before building it, thanks...

is there a parts list for these? then we know what to buy and order to make it. i'm good at soldering but not good at understanding what to order by just looking at the picture.

Damn it's been about 2 years since I did work on a breadboard in uni, can't remember a lot.

There's no need to cut anything from the schematics - if you want to build one of them, just make the teensy one at the top left - it's the easiest one (and probably the cheapest one too).

Someone capable of cutting out the not needed stuff from these shematics?

The USB Port, Controller, LEDs, Crystal, Resistors should be enough ?

What about the button thise things have? Those are for programming mode right?

This is a good schematic from joohan:

USB Dongle for 64pin Atmels, with integrated USB connector, now also for 32pin

I made a quick & dirty usb dongle board for running psgroove, so if anyone find it useful then here you go.. Made with freeware Eagle 5.9

The board should be pretty easy to manufacture since only one layer is required(with one jumper, the second layer in the brd file is only GND and can be left out).

The BOM count is minimal, with no "hard to find" parts. I think all 64pin AVR's with USB should work, but I have only tried the AT90USB1287

Tested with psgroove and the default "USER" layout

IC1 AT90USB1287 or similar
C1,C2 15p(10p-30p should be ok)
C3 1u(from atmel datasheet)
C4 1u(not a critical value, can live without it)
C5 0.1u(not a critical value)
LED1,LED2 SMD 1206
Q1 16Mhz OR 8Mhz
R1,R2 500 (about)
R3,R4 27 (about)
R5 2k (anything in 100-100k range)

EDIT: The chips comes with an preprogrammed USB bootloader, use FLIP from for programming
To enter bootloader mode, short the 2pin header, insert the dongle to the PC, force a reset(by shorting the reset TP to ground with a small screwdriver).
After programming remove the short on the header

To test the dongle after programming, insert into a pc and led2 should turn on. If it doesn't then hard force a reset( shorting the reset TP to ground..) I had to do this on 1 out of 3 tested pc's. You should now get a USB connection with ID aaaa:5555
