Gpsrx: common questions

What microcontroller does the Gpsrx use?

The Gpsrx is built around the ESP32-S3-WROOM-1-N8R2, from the ESP32 family.

How big is the Gpsrx PCB?

The Gpsrx measures 152.4 × 92 mm, has 6 copper layers and is 1.559 mm thick.

How many components are on the Gpsrx?

283 components, from 81 distinct parts. The full bill of materials is listed on this page.

Where can I download the Gpsrx design files?

From the bgelb/gpsrx repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the Gpsrx design in my own project?

The repository has no license, so all rights stay with bgelb. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the Gpsrx without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug ESP32 firmware against it before you order a PCB.
