Questions

How big is the SRAD computer PCB?

It measures 80 × 90 mm and has 2 copper layers, 1.6 mm thick.

What parts does the SRAD computer use?

71 parts, built around the RP2040, BME280, W25Q128JVSIQ and MPU-9250. 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 SRAD computer KiCad files?

From the Jhertter/Flight-Computer-2025 repository on GitHub, at the commit this page was made from: the board is SRAD_Design/SRAD_computer.kicad_pcb and its schematic SRAD_Design/SRAD_computer.kicad_sch. PCBKit opens the board in the browser, with nothing to install.

Can I use the SRAD computer design in my own project?

Its repository states no licence, so its author keeps all rights: ask Jhertter before reusing the design.
