A custom circuit board for the HSIS project

Update: 2013.05.23
I had entered an endless analysis / (re)design loop. In an attempt to break out of that I decided to break the problem into parts. The biggest make/break design problem is getting usable photos from the TCM8240. To get that working I designed a breakout board - check out this post

This documents the evolution of my circuit design. The idea is to put as much as possible on a single purpose built board to reduce size & weight. As a bonus, reliability should go up because there are fewer board-to-board connections.

The board will
*Take photographs using something like:
*Acquire GPS coordinates
*Take board temperature
*Take external temperature
*Log all this to a MicroSD card
