Max AVR USB Review –
3. The Chip
7. Our tests
Here it is, one of the first AVR USB out on the market that is designed and manufactured on the USA/EU.
Official Product Description:
The Max AVR USB board is a low-cost demonstration board based on the AT90USB 16kb microcontroller. It allows the quick evaluation of AVR microcontrollers and the AT90USB family.
The key simply plugs into the USB port of a personal computer. Designers can either run demonstration programs or their own application. Using the ATMEL FLIP Software.
The chip comes packaged on a purple bag, with its geniune sticker glued up. After opening the package we found out our first impression with this AVR. We were told that these first batch
will come without housings, however in the near future they will be bundled with a housing to protect our investment. For now at least the chip comes sealed with a plastic protection to prevent
electric shorts if it gets on contact with any conductive surface.
3. The Chip
This little AVR is based on the AT90USB microcontroller. Keep in mind that the chip sold as is wont work to put our PS3 on dev mode, at least not until the proper HEX has been flashed onto
the AVR. The design of these AVR is well known and not a non-standard one, which helps for the porting of the PSGroove onto it or flashing utils. For flashing the hex we need an Atmel software named
FLIP which is available for free
Ok so now were gonna focus on getting this product to work on our beloved PS3. To start this is what is needed:
- PS3 FAT/SLIM (Duh!)
- PC/Laptop to flash the Max AVR the first time
- One original PS3 Game (if you want to test the Backup Manager)
- Free space on Internal/External HDD on the PS3 if plan to use with Backup Manager
- PS3 OS 3.41 or lower installed (if your 3.42 your out of luck)
- PC OS Windows (had some issues with 64bits OS for flashing the AVR, so I recommend 32bit)
- Atmel FLIP 3.4.2 (To flash the AVR. Grab it here http://www.atmel.com/dyn/products/to...p?tool_id=3886)
- A working hex file to flash it with ( check http://maximusavr.blogspot.com/ )
Our first step to get the unit working is doing the flash of the hex. I'll try to sumarayze the steps.
- Install the Atmel FLIP Software
- Connect the AVR on the PC
- Press both buttons on the AVR (RST HWB)
- Release the RST button, then the HWB
- Windows should ask for drivers of the new hardware found. Point them to C:\program files\atmel\flip 3.4.2\usb
- Run FLIP, and flash with the correct hex

The AVR should be programmed with the PSGroove by now, so its time to put it to work. To do so, the first step we need to do is be sure that no other usb device is attached to the PS3.
Verify that the Max AVR should be connected on the first port on the front of the PS3. The unit must have been cold booted (PS3 Fats, move the on/off switch from the back, and PS3 slims
would need to have the power cord disconnected/connected). After that, we need to turn on the PS3, and just after hitting the ON button, we need to press the EJECT button.
After a few seconds, first the AVR will lit up a red led, and after 1 or 2 seconds more, it will change to green. Once it changes to Green it means that the exploit was succefully done.
Congratulations, now you have a PS3 running on DEV mode If you want to install ipk packages (ie ps3 ftp server or bacukp manager) you need to copy the files onto a usb mass storage device,
and you will be able to install them from the Game menu inside the PS3.
Here is a small video showing how to boot up the ps3

7. Our tests
With 24 hour of testing, the game compatibility was exactly the same as the PSGroove. I suggest you check this table before doing your backups to see if there arent any known issues of it.
After playing around 1 day with this AVR, I must say I was excited to see a PS3 see the light of the day. I really want to see what open source projects can come to life onto the PS3 with
the amount of processing power the PS3 has
+ Uses open source project for its code, making it a safe product
+ Easy operation
+ No opening of the PS3 required
- Backup Managers from other products (ie PSJailbreak 1.1) might not directly work on this (until some clever guys find a way to patch from PSGroove/Binary to emulate/crack it)
- Earliers adopters of this AVR might not get a housing
