Just a short update, I've been working on designing a PCB with Eagle. At this stage it will include a header for the GPS module, ESP8266-12E and the circuitry from the Openlog. The layout is almost finished and I'll upload to GitHub when it is complete.

This process has made me consider two things.

1. Can I design a nice module for the Ublox Neo-6m GPS that includes a breakout of the time pulse signal? I cannot find one online currently and the chip by itself is so cheap! This may be a spin off project.
2. Can I get the ESP8266 to write the data directly to the SD card? This will require initialising the file system and writing over SPI. I'm sure it's been done but I haven't researched enough on it. This would have the added bonus of removing around half of the components from my board!! This will be something for the next iteration.

The firmware for the ESP8266 is likewise almost ready and that will be uploaded to GitHub aswell.
