Pyra datasheets

Does anyone have a directory full of datasheets for the various chips used in the Pyra? I've been reading up on a few things but keep having to search for the datasheets. I expect someone has got all these in one place already though.

If not, is it ok if I create a list of datasheet links here or on the wiki?

Great work!
Some comments for completion (if you want to make a Wiki Page) when comparing to the mass production release:
* TCA6424ARGJ has been replaced by pin compatible NXP PCAL6524HEAZ
* RF-connectors are U.FL type Molex 73412-0110 and Murata MM8430-2610RB3
* Speakers are Seltech GR1813L025UN8 (may have been discontinued) or compatible
* TS3A5223RSW and its function has been removed because it can't avoid leakage current into the WWAN module if that is powered off
* 3G/4G Antenna is Antenova A10393 RUBRA

Sorry for the confusion darling :) I forgot to do version tracking there. It looks like you've worked through the list on the wiki now anyway?
