- | The schematics only use symbolic labels for most components, and abstract names made up by Nokia for some of the large chips (e.g. GAYA, RAPUYAMA). However at least most resistors and capacitors have their size printed next to them. So the simpler the component, the harder it gets to tell what it actually is - except for capacitors and resistors. For a lot of chips you can read the actual printing from body of component, by looking at the photos p. 14, 15 and at [http://maemo.cloud-7.de/Gallery-N900-exploded | + | The schematics only use symbolic labels for most components, and abstract names made up by Nokia for some of the large chips (e.g. GAYA, RAPUYAMA).

This webpage<ref name="teardown BOM">http://www2.electronicproducts.com/Nokia_N900_Mobile_Phone-whatsinside_text-90.aspx</ref> has a pretty decent list of components from a reverse engineering teardown effort by isuppli.com. Almost a BOM, if only they had added the symbolic labels or exact component locations to link back to the schematics. Comes even with links to datasheets, physical dimensions of component, etc pp. | This webpage<ref name="teardown BOM">http://www2.electronicproducts.com/Nokia_N900_Mobile_Phone-whatsinside_text-90.aspx</ref> has a pretty decent list of components from a reverse engineering teardown effort by isuppli.com.
