Gps rx: common questions
What microcontroller does the Gps rx use?
The Gps rx is built around the ICE40UP5K-SG48I, from the FPGA family.
How big is the Gps rx PCB?
The Gps rx measures 16 × 16 mm, has 4 copper layers and is 1.0588 mm thick.
How many components are on the Gps rx?
36 components, from 20 distinct parts, with part numbers taken from the project's own BOM. The full bill of materials is listed on this page.
Where can I download the Gps rx design files?
From the Keyaan-07/gps-rx repository on GitHub, which has the KiCad layout, the schematic and the BOM; the links under Design files point to each one.
Can I use the Gps rx design in my own project?
The repository has no license, so all rights stay with Keyaan-07. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the Gps rx without the hardware?
Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug FPGA firmware against it before you order a PCB.
