The FAQ is woefully incomplete with regard to the hardware details, and it doesn’t provide much more information than the product page. Though there have been multiple blog posts in the past couple of months in the “Hardware” category, the last blog post that actually had substantial, new information on hardware development was the February update. The April update only said that the board schematic was being worked on and that cameras were being looked. at. The May update only contained one sentence about hardware, and it was just to say that the schematic was still being worked on.
The only component present in the FAQ spec list that wasn’t present in the February update is the DAC. The DAC was confirmed in a forum post at the end of March, but wasn’t included in any official updates that I’ve seen.
Surely there has been more progress in the last four months than just choosing a DAC. If not, then I don’t see how Purism plans to ship finished phones with three months left to do everything else.
