GPSDO: common questions
What microcontroller does the GPSDO use?
The GPSDO is built around the 511-STM32H562RGT6, from the STM32 family.
How big is the GPSDO PCB?
The GPSDO measures 100 × 100 mm, has 4 copper layers and is 1.6 mm thick.
How many components are on the GPSDO?
179 components, from 51 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 GPSDO design files?
From the AntonSievering/TRACKER 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 GPSDO design in my own project?
The repository has no license, so all rights stay with AntonSievering. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the GPSDO without the hardware?
Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug STM32 firmware against it before you order a PCB.
