Re: [psas-avionics] GPS v3 board is done!
First pass comments/questions: Sheet 2: Question not answered about Analog ground On sheet 4 AGND is used with the 2.85VA supply, so yes? Sheet 4: TODO note on sheet 4 I'd like to use MAX Clockout too...review how much time delay in U5? Probably not significant unless it creates a hold time issue with Ix/Qx data... CPLD VDDIO(1,2) are at 3.3v, but MAX is 2.85V I/O? Is this a mismatch? Sheet 6: Consider changing VSSA connect to AGND? GTG, I'll try to look more later.

[psas-avionics] GPS v3 board is done!
Hey! The v3 GPS board is done. Please pull and give me feedback as soon as you can, I'd love to ship this out ASAP. https://github.com/psas/gps-rf-board Things to think about: - Split in ground/power planes - cute or stupid? - What else is missing from the board? - Probably not enough test points? Next: make the BOM, and get ready to send this off!
