Questions
How big is the RB1 PCB?
It measures 70 × 70 mm and has 2 copper layers, 1.6 mm thick.
What parts does the RB1 use?
20 parts, built around the RFM69HW. 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 RB1 KiCad files?
From the DrGlaucous/FightingRobot repository on GitHub, at the commit this page was made from: the board is RB1/Schematic/Mainboard/Mainboard.kicad_pcb and its schematic CommonFirmware/RetroTransmitterConversion/Schematic/Schematic/Schematic.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the RB1 design in my own project?
Its repository states no licence, so its author keeps all rights: ask DrGlaucous before reusing the design.
