Technical information on the bSquare Maui (power handheld)

Update :

03.11.2006: I disassambled the Maui and soldered a serial port in to the Maui. Here the results (with pictures).

Thanx to H/PC-Fan and Electron (link to forum) I got the desired information about the video chipset!

Video : S1D13806 (EPSON)
Touchscreen : PIC 16F874

Why :

To get a solid base for building the kernel for the Maui, we need some detailed technical information.

Standard info :

The official bSquare customer information can be found here. This pdf gives an overview over the device.
So the following is public:

Processor	XScale pxa250 @ 400 MHz
ROM	32 MB
RAM	64 MB
User Storage	10 MB
SDIO slot	MMC/SD up to 1 GB, Socket SD 802.11 (long version) WLAN
IrDA	115 kbps
USB (datasheet)	USB slave

Opening the Maui :

To gather more info I opened the Maui. This did not bring much details, because the display is taped to the motherboard
and I did not want to destroy the tape. Therefore I could not take a look at the chip numbers :-(


Back	Front

What I found on the back:

Battery	ATL 3.7V / 1860 mAh 3943131 325351401142
Plate number	404150003644(3104-CB)
GSM Module	Ubinetics GM404 (09-GM404-05004289)
Little chip (Audio - datasheet)	WM xwm873 34aag2x

What I found on the front:

Back of the motherboard	MLV1A 94VD 0704 BSQUARE CORP 250-110466-02 REV A
Display	84103901 FP241030466 (Toshiba LTM04C380K 18 bit TFT)
Display wire	TT04640010

Using the PHM Device Manager :

At http://www.phm.lu/Products/PocketPC/DevMgmt/ I found a great freeware device manager. When installing
the software just answer that you want to proceed, alltough the software seems not suitable for the device. You will
need to put this aygshell.dll in the folder \Program Files\PHM System Tools to make it run properly.

The registry :

Also of interest is the content of the registry. So here you can view the default registry (942 kB html).

This is all we have at the moment, but there soon will be more. I wrote a mail to bSquare, if they can give me more
detailed information and I hope to hear from them.

Lets have fun on Maui ...
