u-blox SAM-M8Q GPS Featherwing

Revision 2.0 is here! It involves a new layout for the GPS module, with the top layer being the primary ground layer. This should improve the GPS signal because it gives a larger ground plane for the built-in antenna. I also added some user configuration on the bottom, where the user can close jumper pins to connect certain GPS output pins (INT, PPS, ~RESET, ~SAFE) to prechoosen Feather pins. The new .GBR files and KiCad Design Files will be uploaded to Hackaday shortly.

Below are some photos of the traces and KiCad renderings of the board.

I have uploaded an archive of the KiCad Design files and .GBRs for this project. Please note that at the current state, the hardware has only been designed, but not built or tested. Because of this, I can not guarantee that hardware will work 100% as intended. But feel free to use these files to make your own boards/build upon them!

Because I have not built or tested this project yet, project specific software does not yet exist. Feel free to make your own though!

If anyone ends up building this, feel free to let me know, as I am interested to see how many errors/improvements can be made.

Rev1.5 just has some small silkscreen changes, mostly to proved power and PPS GPS indicators for the LEDs so the user knows what they are. Very small changes overall, hence 1.5 and not a full revision.

Figured out what components I wanted for this board. Only 16 components needed (excluding the Feather!). The BOM can be found on Octopart. This may change if I find I need additional parts.

Revision 1 is finished! Rev 1 consists of a basic layout of all necessary components, with some problems. Due to space constraints of the Feather footprint, there are some signal lines that really shouldn't be where they currently are. Future revisions will hopefully fix that by either expanding the board outline/footprint or moving the GPS module to an area with less pins.
