README
README.mdGPS Receiver
GPS-RX is a custom-hardware, low-power GPS receiver that is just 16x16mm in size. This receiver does not have any COCOM limits and is fully customisable. It uses UART to communicate with other external controllers and takes a 3.3 volt input. Unlike other GPS receivers, there are no speed or height based limits and can go to any height or any speeds. It is built like a really small module and can be built and assembled by anyone and used basically everywhere. I built this project to learn verilog and also because this seems really cool! The ice40up5k from lattice semiconductor is the FPGA that processes the GPS signals.
Assembly instructions
- Order the PCB from the gerber files in the production folder. Get two stencils(one for the top and one for the bottom).
- Either get PCBA, or solder the components yourself.
- If soldering yourself, place the top side stencil over the top side and apply paste. Place all the components.
- Reflow the top side.
- Do the same process for the bottom side!
- Program the firmware by connecting to the test points.
- Your receiver is ready!
Note about firmware: GPS firmware development without the actual board will be really hard, thus i am not writing the firmware right now.

Questions
How big is the Gps rx PCB?
It measures 16 × 16 mm and has 4 copper layers, 1.06 mm thick.
What parts does the Gps rx use?
45 parts, built around the ICE40UP5K-SG48I, MAX2769CETI+, W25Q16JVUXIQ and 1XXB16368MBA. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the Gps rx KiCad files?
From the Keyaan-07/gps-rx repository on GitHub, at the commit this page was made from: the board is hardware/gps-rx.kicad_pcb and its schematic hardware/gps-rx.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Gps rx design in my own project?
Its repository states no licence, so its author keeps all rights: ask Keyaan-07 before reusing the design.
