Great job!

With the help of ThoughtFix's disassebly instructions, itT member sdrman risks voiding his Nokia N800's warranty and decides to remove all the metal shielding covering the device's chips.Â* Along with confirmation of a FM stereo chip inside, a USB power manager chip is also revealed. Does this mean we can expect USB powered accessories for the Nokia N800 in the future? Two surprises in one day! This is getting interesting... View sdrman's full post and hi-res images of the N800's main board [ 300dpi (mirror), 1200dpi (mirror) ].

The shields are not soldered down, but it's almost impossible to remove them without bending any of the little tabs. They can be bent back, but it's easy to tell that they were removed.

in contrast/compare, did someone do a full list of 770 chips and parts and jams and jellies? would make for a nice wiki page if done with columns of which has what, the exact part #, the function...

Network adapters might work, but it could be iffy. Of course if USB host is enabled the first thing you could do is plug it into a hub but I digress.

Great job!

Thank you Thoughtfix for the disassembly instructions.
The shields are not soldered down, but it's almost impossible to remove them without bending any of the little tabs. They can be bent back, but it's easy to tell that they were removed.

Please don't do this!! It will void your warranty, and you could easily ruin your tablet.
My Incomplete list of part lookups:
Part Label ----- Description
PJMI ----- tps65030 USB-OTG Power Manager 5v 100mA
TUSB6010 ------- USB-OTG Controller
TSC23031 ------- Related to TSC2301? Touch Screen Controller
ST2378E ------ Level Translator
TEA5761UK ------ FM Stereo receiver
STLC4550 ----- Wireless Lan
csr 41814 ------- Bluetooth
I guess the FM radio is no longer news, but the USB power manager looks interesting. This should mean that (when Nokia is ready) the N800 will offer a powered USB host.
