Revision as of 22:29, 16 June 2010

An N900 schematic appears to be at [1]

This might not be the exact version of the schematic used to make the phone.

Revision is given as 2JH_21A on the schematic. However, the pictured PCB in the schematic is 2JH_20 - see above the third row from the right keys. A dissasembled purchased n900 showed a revision number of 2JH_21[2].

This is a brief list of what's where on the schematic. It generally only includes major components, and any minor components that have a direct bearing on software.
