Questions

How big is the Testboard PCB?

It measures 85 × 60 mm and has 2 copper layers, 1.6 mm thick.

What parts does the Testboard use?

31 parts, built around the NCP1117DT33T5G and PCA9535CPW,118. 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 Testboard KiCad files?

From the probe-rs/hive repository on GitHub, at the commit this page was made from: the board is concept/testboard/testboard.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.

Can I use the Testboard design in my own project?

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