Questions

How big is the Prox dev board PCB?

It measures 10 × 8.5 mm and has 2 copper layers, 1.6 mm thick.

What parts does the Prox dev board use?

3 parts, built around the LTR-303ALS-01. 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 Prox dev board KiCad files?

From the TheColonelYoung/TBS---Flash-micro---Prox_dev repository on GitHub, at the commit this page was made from: the board is prox_dev_board.kicad_pcb and its schematic prox_dev_board.kicad_sch. PCBKit opens the board in the browser, with nothing to install.

Can I use the Prox dev board design in my own project?

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