Questions
How big is the RHS 3 PCB?
It measures 51 × 61 mm and has 2 copper layers, 1.6 mm thick.
What parts does the RHS 3 use?
68 parts, built around the ATMEGA328P-AU, CC1101RGP and SI2305CDS. 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 RHS 3 KiCad files?
From the pa-pa/HB-Sec-RHS-3 repository on GitHub, at the commit this page was made from: the board is RHS_3.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the RHS 3 design in my own project?
Its repository states no licence, so its author keeps all rights: ask pa-pa before reusing the design.
