Questions

How big is the MicroRek PCB?

It measures 71.1 × 34.9 mm and has 2 copper layers, 1.6 mm thick.

What parts does the MicroRek use?

64 parts, built around the NRF24L01P-R, FXPQ3115BVT1, LSM9DS1 and TPS630250RNC. 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 MicroRek KiCad files?

From the CalPolySpaceSystems/circuitCAD repository on GitHub, at the commit this page was made from: the board is Projects/MiniRek/MicroRek.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.

Can I use the MicroRek design in my own project?

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