Questions

How big is the Rx prototype PCB?

It measures 121.9 × 101.6 mm and has 10 copper layers, 1.6 mm thick.

What parts does the Rx prototype use?

53 parts, built around the MCP6004-E/P, QMC5883P, 74HC4051 and MPU-6500. 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 Rx prototype KiCad files?

From the SpindlySpider/spindlyVR repository on GitHub, at the commit this page was made from: the board is pcb/rx_proto/rx_prototype/rx_prototype.kicad_pcb and its schematic pcb/rx/rx-proto0.kicad_sch. PCBKit opens the board in the browser, with nothing to install.

Can I use the Rx prototype design in my own project?

Its repository publishes it under the GPL-3.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
